Two quantities A and B are related by the relation A B = m , where m is linear mass density and A is force. The dimensions of B will be

Options

  1. ASame as that of latent heat
  2. BSame a that of pressure
  3. CSame as that of work
  4. DSame as that of momentum

Correct answer

A. Same as that of latent heat

Step-by-step solution

B = A m B = force mass / length   B = force × length mass = energy mass = [ latent   heat ]
