Question

Given below are two statements : Statement-I : An elevator can go up or down with uniform speed when its weight is balanced with the tension of its cable. Statement-II : Force exerted by the floor of an elevator on the foot of a person standing on it is more than his/her weight when the elevator goes down with increasing speed. In the light of the above statements, choose the correct answer from the options given below :

Statement I is true because uniform speed means zero acceleration, so the cable tension balances weight. In Statement II, when the elevator accelerates downward, N = W(1 - a/g), so the normal force is less than the person's weight. Hence Statement II is false.
