Find the magnitude, direction and position of the resultant, if the forces in the above problem are unlike ?

Text Solution

Verified by Experts

The magnitude of the resultant is
R = A - B (greater force - smaller force)
= 15 N - 5 N = 10 N
R = 10 N
Its direction is same as that of the greater force, i.e., A.
Its position is outside MN on the side of A at point 'O' at a distance 'x' from A, such that
`A xx MO = B xx NO`
`15xx x = 5 xx (4+x)`
`15x=20+5x`
`:. x = 2m`
