Question

Why does a block of wood held under water rise to the surface when released ?

Solution

A wooden block held under water floats on the surface on release because it is less dense than water. A substance floats if it is less dense than the fluid in which it is immersed after the external force is withdrawn from it.

  Is there an error in this question or solution?
