Question

pls ans this q pls pls pls

Answer 1

Let two forces be A & B, and the resultant be P.

A + B = 20

P2 = B2 – A2 = (B – A)(B + A)  = 20(B – A)

(B - A) = P2/20 = (4√5)^2 / 20 = 80/20 = 4

B – A = 4 ----------------> EQ 1.

B + A = 20 ----------------------> EQ 2.

then

2B = 24

B = 12 N

A = 8 N
