Question 2

The instantaneous center (IC) of zero velocity for a rigid body in planar motion is the point at which:

Velocity is maximum
Acceleration is zero
The body has zero instantaneous velocity — every other point's velocity is perpendicular to the line joining it to the IC✔️
Angular velocity is zero

Correct Answer Logic:

The instantaneous center of zero velocity is a point where the velocity is zero at that instant. Every point on the body moves perpendicular to its line connecting to the IC, with speed proportional to its distance: $v_P=\omega\cdot r_{P/IC}$.

Constitutional Law QUESTION #5822

Question 6

Congress passes a law providing that 'no federal court shall have jurisdiction to hear any case involving the constitutionality of the Selective Service Act.' Is this law valid?

Yes, because Article III gives Congress power to make 'exceptions and regulations' to the Supreme Court's appellate jurisdiction.✔️
Yes, because military matters are 'political questions' beyond judicial review.
No, because Congress cannot strip the Supreme Court of all jurisdiction over a federal constitutional issue.
No, because it violates the Separation of Powers by dictating the outcome of cases.

Correct Answer Logic:

Under Article III, Section 2, Congress has the power to regulate and limit the appellate jurisdiction of the Supreme Court and to define the jurisdiction of inferior federal courts. While there are limits (it can't destroy the 'essential role' of the court), the MBE generally recognizes this broad 'Exceptions Clause' power.

Question 7

The critical damping coefficient $c_{cr}$ for a spring-mass-damper system is:

$c_{cr} = \sqrt{km}$
$c_{cr} = 2m\omega_n = 2\sqrt{km}$✔️
$c_{cr} = k/\omega_n$
$c_{cr} = m\omega_n^2$

Correct Answer Logic:

Critical damping: $\alpha=\omega_n$ where $\alpha=c/(2m)$. Hence $c_{cr}=2m\omega_n=2m\sqrt{k/m}=2\sqrt{km}$.

Physics QUESTION #7318

Question 10

The position of a particle is described by $x = 8 + 12t - t^3$ (metres, seconds). The retardation when velocity becomes zero is:

$6\text{ m/s}^2$
$12\text{ m/s}^2$✔️
$24\text{ m/s}^2$
Zero

Correct Answer Logic:

$v = \dfrac{dx}{dt} = 12 - 3t^2$. Setting $v = 0$: $t^2 = 4 \Rightarrow t = 2\text{ s}$

$a = \dfrac{dv}{dt} = -6t$. At $t = 2\text{ s}$: $a = -12\text{ m/s}^2$

Retardation $= \mathbf{12\text{ m/s}^2}$

Question 13

A civil servant is appointed to a post through FPSC and the appointing authority wishes to grant him 8 advance increments at initial pay fixation. The post has sufficient qualified candidates available at the minimum pay scale. Under Annex-I powers for fixation of initial pay what is the CORRECT position?

Up to 6 premature increments may be granted after the FPSC's recommendation regardless of candidate availability
No premature increments should be granted because the requisite qualified persons ARE available at the minimum of the pay scale making the condition for premature increments unsatisfied✔️
The PAO has full discretion to grant any number of advance increments for FPSC-appointed staff
Up to 8 advance increments may be granted since FPSC recommended the appointment

Correct Answer Logic:

Premature increments for FPSC-appointed persons should be granted on the FPSC's recommendations AND in consideration of the fact that suitable persons of requisite qualifications are NOT available at the minimum pay of the post. Since qualified candidates are available at the minimum scale the fundamental precondition is not met and no premature increments should be granted.

Let lions $= l$, parrots $= p$.
$l + p = 15$ and $4l + 2p = 50$
From first: $p = 15 - l$
Substituting: $4l + 2(15-l) = 50 \Rightarrow 2l = 20 \Rightarrow l = 10$
