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 correct Answer is:
10
The angle `theta` between the two vectors is `120^(@)` and not `60^(@)`.
`therefore R=sqrt((10)^(2)+(10)^(2)+2(10)(10)(cos120^(@)))=sqrt(100+100-100)=10` dyne
