Three blocks with masses `m, 2m and 3m` are connected by strings, as shown in the figure. After an upward force `F` is applied on block `m`, the masses move upward at constant speed `v`. What is the net force on the block of mass `2m`? (Take, g is the acceleration due to
As shown in Fig., the two sides of a step ladder BA and CA are 1.6 m long and hinged at A. A rope DE, 0.5 m is tied half way up. A weight 40 kg is suspended from a point F, 1.2 m from B along the ladder BA. Assuming the floor to be friction-less and neglecting the weight of the ladder, find the tension in the rope and forces exerted by the floor on the ladder. (Take g = 9.8 m/`s^2`) (Hint: Consider the equilibrium of each side of the ladder separately.)
