Two forces, each numerically equal to 10 dyne are acting as shown in the following figure.
Their resultant is :

Text Solution

Verified by Experts

The angle `theta` between the two vector is `120^(@)` and not `60^(@)`.
`:. R=sqrt((10)^(2)+(10)^(2)+2(10)(10)(cos 120^(@)))`
`=sqrt(100+100-100)=10` dyne
