Question

A body of mass 0.5 kg moves with a constant speed of 4 m/s around a horizontal circle of radius 1m, the magnitude of horizontal force acting on
body towards the center of circle is --------- N.​

Answer 1

Answer:

Given : m=0.5kg R=1m v=4m/s

Centripetal force F= mv2/R

= 0.5 * 16/ 1

=8 N

Answer 2

Given,

Mass of a body=0.5kg

Speed of body=4m/s

To Find,

Magnitude of horizontal force.

Solution,

Here, mass=0.5kg, Radius=1m, Speed=4m/s

So, Centripetal force ,

F= mv²/R

 = 0.5 ×16/ 1

 =8 N

Hence, horizontal force acting on body is 8N.
