Questions  

(N-1) identical forces of magnitude F act simultaneously on a particle each making an angle of 2πN with the preceding one, the resultant is

a
F
b
2F
c
F/2
d
Zero

detailed solution

Correct option is A

Let say N forces are acting on a particle with equal angular separation. Their resultant will be zero.Now remove any one force.This (N-1) system, will have resultant equal to F.
