Two forces F(1)=1N and F(2)=2N act along...

Two forces `F_(1)=1N` and `F_(2)=2N` act along the lines x=0 and y=0, respectively. Then find the resultant of forces.

A

`hat(i)+2hat(j)`

B

`hat(i)+hat(j)`

C

`3hat(i)+2hat(j)`

D

`2hat(i)+hat(j)`

Text Solution

Verified by Experts

The correct Answer is:
D
`x=0` means y-axis implies `vec(F)_(1)= hat(j)`
y=0 means x-axis `implies vec(F)_(2)= 2hat(i)`
So resultant `vec(F)= vec(F)_(1)+vec(F)_(2)= 2hat(i)+hat(j)`
