If two forces each of magnitude 20N, are acting on a particle such that the first force `(vecE_(1))` is acting along east direction and the second force `(vercF_(2))` is acting along the direction `60^(@)` north of west, then the magnitude of resultant force on particle is

A

`20N`

B

`20sqrt(3)N`

C

`(20)/(sqrt(3))N`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
A
If two forces …………

`|vecF_(1)+vecF_(2)| = sqrt(F_(1)^(2)+F_(2)^(2)+2F_(1)F_(2)cos(120^(@))) = 20N`
