Question : 1

Total: 47

The dimensions of momentum are

MLT
ML^-1T^-1
MLT^-1
ML^-1T

Solution:

Concept:

Momentum is the product of mass and velocity.

Explanation:

Momentum

= \text{mass} \times \text{velocity}

.

The dimension of mass is

M

.

The dimension of velocity is

\frac{L}{T} = LT^{-1}

.

So, the dimension of momentum is:

M \times LT^{-1} = MLT^{-1}

This matches option C.

Answer:

The dimensions of momentum are

MLT^{-1}

.

Correct option: C.
