Centripetal force is 5.61N

given data:-

string length r=85cm

mass =1.5kg

velocity=1.08

Centripetal force= mv2/r= 1.5+1.08*1.08/85

=5.61N

What kind of force is a centripetal force?

Centripetal force is the force exerted on an object moving curvilinearly that is pointed in the direction of the object's axis of rotation or center of curvature. Newton is the symbol for centripetal force. Whenever an object moves, the centripetal force is applied perpendicular to that direction.

How is centripetal force generated?

Gravity is the centripetal force in Newtonian mechanics that drives astronomical orbits. The scenario in which a body travels at a constant speed along a circular path is a typical illustration of centripetal force.
