Two force each numerically equal to `10` dynes are acting as shown in the figure, then find resultant of these two vectors.

Text Solution

Verified by Experts

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