Question
A block of mass m is pressed against a vertical surface by a spring of unstretched length l. If the coefficient of friction between the block and the surface is m. Choose the correct statement.
- if spring constant
, block will not be in equilibrium
- if spring constant is , the normal reaction is
- in the part (B) force of friction is 2mg
- minimum spring constant kmin to keep the block of mass M in equilibrium is
, block will not be in equilibrium
, the normal reaction is
The correct answer is: if spring constant , block will not be in equilibrium
