Three forces acting on a body are shown in figure. To have the resultant force only along the y-directon, the magnitude of the minimum additional force needed si

A

`(sqrt(3))/(4)N`

B

`sqrt(3)N`

C

`0.5N`

D

`1.5N`

Text Solution

Verified by Experts

The correct Answer is:
C
(c ) According to given problem there should be `sumF_(x)=0` In the given figure net force along X-axis .
`(1)/(2)hati+1hati-2hati`
`impliesF=-(1)/(2) hati=- 0.5 hati`
