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 `rArr F_(1)= hat(j)`
y= 0, means x- axis `rArr F_(2)= 2hat(i)`
Resultant `vec(F)= F_(2)+ F_(1)`
`vec(F)= 2hat(i) + hat(j)`
