Can work done by F be = FR
Because In spiral motion
1) F = constant along radial vector

2) Displacement of m along radial vector is collinear to F
• So W = integration( F•ds )
= FR
(I have not considered displacement tangential to F as it's perpendicular to F so W = 0)
So can we equate Net work done By force F = FR
