Question 89: Laws of Motion

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 :

Accepted Answer

Statement I
says that when the weight of an elevator is balanced with the tension of its cable, it can move up or down with a uniform speed. This is true because the weight of the elevator is balanced by the tension in the cable, which allows it to move smoothly and at a constant speed.
Statement II
says that the force exerted by the floor of an elevator on a person's foot is greater than their weight when the elevator goes down with increasing speed. This is false because the force exerted by the floor on a person's foot is equal to their weight, regardless of the speed of the elevator. The person's weight is a constant force and does not change with the speed of the elevator. The apparent weight of a person may change with the speed of the elevator, but this is due to the effects of acceleration and not an increase in the force exerted by the floor.
