Question

vehicle is moving on a track with constant speed as shown in figure the Apparent weight of the vehicle is

Answer 1

Answer:

The weight of the car is given by, m\times gravitational\quad force i.e. mg which acts normal to the surface.

The weight of the car will feel reduced as it moves on the curve by a factor of $\frac { m{ v }^{ 2 } }{ r } \rightarrow (1)$

Where, r is the radius of the curve, m = mass of the car, v = velocity of the car and let us consider it as constant.

From the expression (1), we can be sure that the weight reduction factor is inversely proportional to the radius of the curve as the numerator is nearly constant.

Hence if r is small, then more weight will be there on the car.

From the figure, we can be sure that r is larger at points A and C when compared to B. hence the car will have maximum mass at B.
