Two forces, each numerically equal to 5 ...

Two forces, each numerically equal to 5 N, are acting as shown in the figure. Then the resultant is

A

2.5 N

B

5 N

C

`5sqrt(3)N`

D

10 N

Text Solution

Verified by Experts

The correct Answer is:
B
The angle between the given forces is `120^(@)` and not `60^(@)`
Resultant force is
`|vecR|= sqrt(|vecA|^(2)+|vecB|^(2)+2xx|vecA||vecB|"cos"theta)`
`=sqrt((5)^(2)+(5)^(2)+2xx(5)xx(5)xx(-(1)/(2)))=5N`
