Paper-II (Pharmacognosy and Pharmaceutics-I) QUESTION #2952

Question 3

A prescription requires $250\text{ mg}$ of a drug, but the pharmacy only has a $5\%$ (w/v) solution. How many milliliters are needed?

2 ml
5 ml✔️
10 ml
50 ml

Correct Answer Logic:

$5\%$ w/v means $5\text{ g}$ in $100\text{ ml}$, or $50\text{ mg/ml}$. Calculation: $250\text{ mg} \div 50\text{ mg/ml} = 5\text{ ml}$.

Chemistry QUESTION #1089

Question 4

The ratio of wavelengths of light absorbed by hydrogen atom for $n=2\to n=3$ and $n=4\to n=6$ transitions is:

$\dfrac{1}{9}$
$\dfrac{1}{4}$✔️
$\dfrac{1}{36}$
$\dfrac{1}{16}$

Correct Answer Logic:

For hydrogen: $\frac{1}{\lambda} = R_H\left(\frac{1}{n_1^2}-\frac{1}{n_2^2}\right)$. Transition 1 ($n=2\to3$): $\frac{1}{\lambda_1}=R_H\left(\frac{1}{4}-\frac{1}{9}\right)=R_H\cdot\frac{5}{36}$. Transition 2 ($n=4\to6$): $\frac{1}{\lambda_2}=R_H\left(\frac{1}{16}-\frac{1}{36}\right)=R_H\cdot\frac{5}{144}$. Ratio: $\frac{\lambda_1}{\lambda_2}=\frac{5/144}{5/36}=\frac{36}{144}=\frac{1}{4}$.

Question 15

In RC beam shear design per ACI 318 (simplified), the nominal concrete shear strength $V_c$ for a rectangular beam with $f'_c$ in MPa, $b_w$ in mm, and $d$ in mm is:

$V_c = 0.33 \lambda \sqrt{f'_c} \cdot b_w \cdot d$ (N)
$V_c = 0.17 \lambda \sqrt{f'_c} \cdot b_w \cdot d$ (N)✔️
$V_c = 0.17 \lambda f'_c \cdot b_w \cdot d$ (N)
$V_c = \lambda \sqrt{f'_c} \cdot b_w \cdot d$ (N)

Correct Answer Logic:

Per ACI 318 simplified equation: $V_c = 0.17\lambda\sqrt{f'_c} \cdot b_w \cdot d$ (in Newtons, SI units). For normal weight concrete $\lambda = 1.0$. The more detailed equation also accounts for $N_u$, reinforcement ratio, and moment. The factor 0.33 applies in the more conservative detailed method for certain conditions.
