Three vectors each of Magnitude A are acting at a point such that angle between two consecutive vectors in the same plane is = 60. then magnitude of resultant is

The resultant force = Zero(0)

Explanation: resolving the vector into X and Y component

AB = A

BC = -A cos60 + A sin60

= - A/2 + 0.866A

CA = - A cos60 - A sin 60

= -A/2 - 0.866A

Sum of the magnitude in the X component

A - A/2 - A/2 = 0

Sum of the magnitude in the Y component

- 0.866A + 0.866A = 0

Resultant vector = root(X^2 + Y^2) = 0

Therefore

AB + BC + CA = 0

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
