Solution

The correct option is C Centripetal force remains same
For a particle moving in a circular path of radius 'r' with an angular speed ω, centripetal force is given by
F=mrω2
Initially, r1=r,ω1=ω
F1=mr1ω21=mrω2
Finally, r2=4r,ω2=ω2
F2=mr2ω22=m(4r)(ω2)2=mrω2=F1
centripetal force remains the same.
