Question

Which of the following does not have the dimensions of force

A. Potential gradient
B. Energy gradient
C. Weight
D. Rate of change of momentum

With clear explanation please.....
I'll mark the brainliest

Answer 1

Answer:

option A

Explanation:

The gradient of the gravitational potential gradient is the gravitational electric field (i.e. force acting on unit mass).

E→=−∇ϕ

which has dimensions of N/Kg

Weight is the force exerted by the gravity. So, it will have dimensions of force.

Energy gradient is simply the force vector. So, it will have dimensions of force.

By newton's 2nd law, Rate of change of momentum is the net force. So, it will have dimensions of force.

Hence, Option A is correct.
