Answer:

2 N

Explanation:

Frictional force balances the weight of the block.

F_{f} = μN

F_{f} = (0.2)(10) = 2 N

As the block is in equilibrium, (As it is stationary) The weight of the block must cancel out the frictional force,

According to Newton's second law, F_{net} = ma

⇒ W - F_{f} = m(0)

⇒ W = F_{f}

Hence weight of the block is 2 N.
