3 forces acting on a particle are given by
(1) `(2hati+3hatj-2hatk)N`
(2) `(3hati+hatj-3hatk)N`
(3) `(-5hati-2hatj+hatk)N` The particle will move in

A

X - Y plane

B

Y - Z plane

C

X - Z plane

D

Along X-axis

Text Solution

Verified by Experts

The correct Answer is:
B
Sum of the forces (1),(2) and (3)
`=[2hati+3hati-5hati]+[3hatj+hatj-2hatj]+[-2hatk-3hatk+hatk]`
`=[2hatj - 4hatk]`
`therefore` The particle will move in the Y - Z plane as there is no x-component.
