Answer:
Weight of the block(W) is balanced by the frictional force due to the wall
W = f...... (1)
f = μN........(2)
Where 'μ' is coefficient of friction and 'N' is normal force
Using (1) & (2)…we get
W = μN = 0.2*10N = 2N
W = 2N (weight of the block)

Answer:
2 N
Explanation:
Frictional force balances the weight of the block.
= μN
⇒ = (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, = ma
⇒ W - = m(0)
⇒ W =
Hence weight of the block is 2 N.
