Question

(N-1) identical forces of magnitude F act simultaneously on a particle each making an angle of $\frac{2 π}{N}$ with the preceding one, the resultant is

Moderate

A

F
B

2F
C

F/2
D

zero

Solution

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.
