Question

Find the dimension of V=√GM/R^2

Answer 1

Answer:

Explanation:

Equation - V = ​√2 GM/R

Dimension of LHS = velocity(m/s) = M0 L1 T-1  OR   L1 T-1

Dimension of RHS = √2 GM/R

Since dimension of Universal Gravitational Constant (G) is M-1L3 T-2

Therefore, Dimension of √2 GM/R = M-1L3 T-2x M1 / L1​       [​√2​ is a constant , it has no dimension]

M0L2T-2   OR   L2T-2

Now , since Dimension of LHS ≠ Dimension of RHS

Therefore, it is incorrect.
