Question

Write dimensional formula of

(i)Torque (ii) Resistance (iii) Gravitational constant (iv) Force​

Answer 1

Answer:

Or, I = [M1 L2 T0] × [M0 L0 T-2] = [M L2 T-2]. Therefore, the torque is dimensionally represented as [M L2 T-2].

Explanation:

Therefore, resistance is dimensionally represented as M L2 T-3 I-2.

Or, G = [M1 L1 T-2] × [L]2 × [M]-2 = [M-1 L3 T-2]. Therefore, the gravitational constant is dimensionally represented as M-1 L3 T-2.

Or, F = [M] × [L1 T-2] = M1 L1 T-2. Therefore, Force is dimensionally represented as M1 L1 T-2.

Answer 2

1. force = M×A

mass×accelaration

2. reilsistance = ML²T³I²

3. Torque = [ML²T²]

4. Gravitational constant = MLT ² = G.M.M
