Three forces are acts along three sides of equilateral triangle of maginitude p,2p,5p.wht is the reultant force magnitude???

Dear ashutosh,

You resolve the components of the force.

Net force in x direction is : p-2pcos60-5p cos60 i

Net force in y direction: 2psin60-5psin60

Resultant will be sqrt of the sum of the squares of the two forces.
