Question

101. Two equal forces are acting at a point with an
angle of 60° between them. If the resultant force
is equal to 403 N, then magnitude of each
force is
(A) 40 N
(B) 20 N
(C) 80 N
(D) 10 N

02. Velocity and​

Answer 1

Answer:

esultant =  where angle between two forces is α.....

here α is 60* and both A and B are equal...let them be x....

= 20√3

2x²+2x²(1/2) = 1200

3x²              = 1200

x²                = 400

x                 = 20

therefore magnitude of each of the forces is 20N...
