Solution

The correct option is A $30 N$
Since the surfaces do not have friction, there is no force acting on $3 kg$ body in horizontal direction.
Hence,

$N = 3 g = 3 \times 10 = 30 N$

Find the force exerted by 3 kg body on 1 kg assuming all surfaces are smooth (g=10 m/s2)

The correct option is A 30 NSince the surfaces do not have friction, there is no force acting on 3 kg body in horizontal direction. Hence, N=3g=3×10=30 N
