NEET Physics (general) Assertion Reason Question

Type: Assertion Reason-assertion-Medium-Class 11

Assertion (A): The equation 12mv2=mgh\frac{1}{2} m v^2 = mgh is dimensionally consistent. | Reason (R): Both sides of the equation 12mv2=mgh\frac{1}{2} m v^2 = mgh have the same dimensions of [ML2T2][M L^2 T^{-2}].

A

Both A and R are true and R is the correct explanation of A.

B

Both A and R are true but R is not the correct explanation of A.

C

A is true but R is false.

D

A is false but R is true.

Correct Answer

Option A

Detailed Explanation

The equation 12mv2=mgh\frac{1}{2} m v^2 = mgh is dimensionally consistent as both sides have dimensions [ML2T2][M L^2 T^{-2}], confirming the reason.
