Answer:
F n = 0.2 N
Explanation:
given, Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â Â
you are exerting force of 10 N on the ball.
mass of the ball = 1 kg       Â
acceleration due to gravity  = 9.8 m/s²
normal force on the ball = ? Â Â Â Â Â
normal force is force exerted by the object to counteract the force from other object. Â Â Â Â Â Â Â Â
normal force acting on the ball will be
F n = F - mg             Â
F n = 10 - 1 × 9.8            Â
F n = 10 -9.8 Â Â Â Â Â Â Â Â Â Â
F n = 0.2 N Â Â Â Â Â Â
Hence, normal force acting on the ball is equal to 0.2 N
