NEET Physics Physical Quantities MCQ Question
Type: MCQ-diagram based-Hard-Class 11
Consider a diagram showing a pendulum setup where the time period T is expressed in terms of the length l and gravitational acceleration g. Which of the following expressions correctly represents the relationship between T, l, and g using dimensional analysis?
A
T = k * sqrt(l/g)
B
T = k * l^2 / g
C
T = k * l * g^2
D
T = k * g / l
Correct Answer
Option A
Detailed Explanation
According to the NCERT context, the time period T of a pendulum is dimensionally represented as T = k * sqrt(l/g), where k is a dimensionless constant.
