Question

(more than one correct option)
if the resultant force is always perpendicular to the motion of
a particle :
1 KE remains constant 2 work done =0 3 speed is constant 4
velocity is constant
give reason also

Workdone = FScosθhere θ = 90 so work done is zero
In circular motion, speed remains constant

(more than one correct option) if the resultant force is always perpendicular to the motion of a particle : 1.KE remains constant 2. work done =0 3.speed is constant 4.velocity is constant give reason also
