A smooth wedge A is secured inside a chamber suspended from a fixed ceiling near the earth's surface. A block B positioned at the top of the wedge requires a time T to slide down the wedge's length. If the block is placed at the top of the wedge and the cable holding the chamber is snapped at that exact instant, the block will

Step-by-step solution

When the cable holding the chamber is snapped, the chamber and the wedge fall freely under gravity with a downward acceleration g . In the non-inertial reference frame of the freely falling wedge, a pseudo force of magnitude mg acts upwards on the block B . The effective acceleration due to gravity in the frame of the wedge is g_ eff = g - g = 0 . Since the effective gravity is zero, the normal reaction between the block and the wedge becomes zero, and there is no force component along the incline to accelerate the
