If XYZ is an equilateral triangle. Then ...

If `XYZ` is an equilateral triangle. Then the resultant of the three forces shown in the figure is :

A

`F`

B

`Fsqrt(20)`

C

`Fsqrt(21)`

D

`3F`

Text Solution

Verified by Experts

The correct Answer is:
C
If `XYZ` is an …………

`= sqrt(12F^(2)+9F^(2))` , `=sqrt(2+F^(2)) = F sqrt(21)`
