Question

what is the work done by the centripetal force in moving the body on half the circumference of the circle​

Answer 1

Answer:please give me the brainliest answer

The work done by a centripetal force in moving a body on the circumference of the circle is always zero. we know that work done by a force is given as

W = F d Cosθ

please give me the brainliest answer plzzzzzz

where  F = force , d = displacement , θ = angle between force and displacement

in case of work done by the centripetal force , the force is towards the center along the radius and the displacement vector is along the tangent to the circle . we know that the angle between the radius and tangent is always 90. hence the angle between centripetal force and displacement is 90

since Cos90 = 0

hence W = 0             in case of centripetal force

Explanation:

Answer 2

Answer:

its zero

Explanation: displacement is zero
