Q1:

The dimensional formula of force is

A MLT-2

B M-1LT2

C ML-2T

D M-1L2T-2

E none of these.

ANS:A - MLT-2

The dimensional formula of force can be derived from Newton's second law, which states that force (F) is equal to mass (m) times acceleration (a): F=ma The dimensional formula for mass (M) is M, for acceleration (A) is LT−2. Thus, the dimensional formula for force (F) is: F=M×LT−2=MLT−2 So, the correct option is: MLT^−2.
