Questions
In the figure, pulleys are smooth and strings are massless, m1 = 1 kg and To keep m3 at rest, mass m3 should be
detailed solution
Correct option is A
m3 is at rest. Therefore,2T = m3 g …(i)Further, if m3 is at rest, then pulley P is also at rest.Writing equations of motion, m1g - T = m1a …(ii) T - m2g = m2a …(iii)Solving Eqs. (i), (ii) and (iii), we get m3 = 1 kgTalk to our academic expert!
