Question

A body covers and fourth for the circulor path of radius (R). find the distance and displacement

Answer 1

Answer :

Radius of the circular path = R.

The body covers one fourth distance in the circular path.

Now, We know the circumference of the circle = 2πr.

[Circumference = Distance travelled by the body]

The Distance travelled [one fourth of the circumference] = 2πr/4 = πr/2 m.

Additional Information :

• Distance is the length of the total path travelled by a body.

• It is a scalar quantity.

• Displacement is the shortest distance between the initial position and the final position of the body.

• It is a vector quantity.

• Speed is the distance travelled per unit time.

• Velocity is displacement per unit time.

• Speed is a scalar quantity.

• Velocity is a vector quantity.
