As given the trolley is falling freely.That means the acceleration due to pseudo force will be equal to g( gravity)Now as the trolley falls freely it will experience a psedoforce in the opposite direction of its motion. MgsinA = Mg( MgsinA is due to inclined plane) Therefore. SinA = 1 or A = 90

question is incomplete. A complete question is ----->A trolley is falling freely on inclined plane as shown in the figure. The angle of string of pendulum with the ceiling of trolley is (α) equal to

(1) θ° (2) 90° – θ° (3) 90° (4) 0°

answer : option (3) 90°

explanation : Let T is the tension acting on trolley.

so, component of tension along the inclined plane is .

if m is the mass of system of trolley,

then, component of weight along the inclined plane is

acceleration of the trolley = acceleration of the bob in the trolley as bob is in the equilibrium in frame of the trolley.

so, net force along the plane,

for free falling on inclined plane, a = along the plane.

so,

hence, option (3) is correct
