Question

Two blocks of masses m 1 = 4 kg and m 2 = 2 kg are connected to the ends of a string which passes over a massless, frictionless pulley. The total downwards thrust on the pulley is nearly, 27 N, 54 N, 0.8 N, Zero

MARKS App · Accepted Answer

T = 2 m 1 m 2 m 1 + m 2 g = 2 × 4 × 2 × 10 4 + 2 = 160 6 = 26.6 = 27 N Total downward thrust on the pulley = 2 T = 2 × 27 = 54 N
