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

`hati+2hatj`

B

`hati+hatj`

C

`3hati+2hatj`

D

`2hati+hatj`

Text Solution

Verified by Experts

The correct Answer is:
D
`x=0` means y-axis`impliesvecF_1=hatj`
`y=0` means x-axis `impliesvecF_2=2hati`
So resultant `vecF=vecF_1+vecF_2=2hati+hatj`
