Question

The quantity which has the same dimensions as that of gravitational potential is

• A. latent heat
• B. impulse
• C. angular acceleration
• D. specific heat capacity

Answer 1

Answer: (A)

latent heat

Answer 2

Dimensions of gravitational potential $=\frac{\text { Dimension of work }}{\text { Dimension of mass }}$ $=\frac{\left[ ML ^{2} T ^{-2}\right]}{[ M ]}=\left[ L ^{2} T ^{-2}\right]$ and dimension of latent heat $=\frac{\text { Dimensions of }[ Q ]}{\text { Dimensions of }[ M ]}$ $=\frac{\left[ ML ^{2} T ^{-2}\right]}{[ M ]}$ $=\left[ L ^{2} T ^{-2}\right]$
