Question

P and 3p are two forces acting in nw and ne direction respectively.find the resultant of the forces by resolving them into perpendicular components.

Answer 1

Hey there,

3p in NE direction = 3pcos45° in E direction.
p in in NW direction = pcos45° in W direction.

Since the forces are in opposite direction,
Hence, resultant force=

3pcos45°-pcos45°
=2pcos45°
=2p/√2
=p√2 NEWTON
