STANDARD Physics Dimensional Equations MCQ Question
Type: MCQ-conceptual-Medium
If the energy, E = Gⁿhᵖcʳ, where G is the universal gravitational constant, h is the Planck's constant and c is the velocity of light, then the values of p, q and r are, respectively
A
−1/2, 1/2 and 5/2
B
1/2, −1/2 and −5/2
C
−1/2, 1/2 and 3/2
D
1/2, −1/2 and −3/2
Correct Answer
Option A
Detailed Explanation
Applying the principle of homogeneity of dimensions, we solve the equations derived from the dimensional formula to find p = −1/2, q = 1/2, and r = 5/2.
