Question

Two bodies P and Q of masses 10kg and 15kg respectively are connected by a light inextensible string.mass 15kg is at free fall pulling mass 10kg.P is placed on a tough surface of the coefficient of friction, 0.5. if the acceleration due to gravity is 10m/s², calculate the magnitude of the:

normal reaction on P

Answer 1

100 N

Step-by-step explanation:

ΣFy = 0

N - wP = 0

N - mP•g = 0

N - 10 × 10 = 0

N = 100 N
