Question

A bus is moving along a curved path. During the motion of the bus, the direction of force on it
a) remains same
b) changes continuesly
c) is directed in backward direction
d) is directed in downward direction​

Answer 1

Answer:

During the motion of the bus, the direction of the force on it changes continuously i.e.option(b).

Explanation:

The force on a curved path is calculated as,

$\mathrm{F=\frac{mv^2}{r} }$        (1)

Where,

F=force acting on a body

m=mass of the body

v=velocity which the body is moving on a circular path

r=radius of the curved path

The magnitude of the instantaneous velocity, often known as speed, is constant in a circular motion. The path is constantly shifting. As the force is the vector quantity so the direction of the force will change continuously.

During the motion of the bus, the direction of the force on it changes continuously i.e.option(b).

Answer 2

Answer:

Option(b).is correct

During the movement of the bus, the path of the Force on it changes constantly

Explanation:

During the movement of the bus, the path of the pressure on it changes constantly

The pressure on a curved route is calculated as

F=mv^2

Where,

F- Force performing on a bodym-mass of the body

V-speed which the frame is transferring on a round path

r-radius of the curved path

The importance of the immediate speed, regularly referred to as speed, is steady in a round movement. The route is continuously shifting. As the pressure is the vector amount so the path of theforce will extrade constantly.

Hence , The correct Option is B

That is ,A bus is moving along a curved path. During the motion of the bus, the direction of force on it changes continuously.
