A force is inclined at an angle of `30^(@)` from the horizontal. If the horizontal component of the force is 20N,calculate the vertical component.

Text Solution

Verified by Experts

` because A_x= A cos theta " "therefore 40 = A cos 60^(@) = (A)/(2) rArr A = 80 N `
Now `" "A_y= A sin 60 ^(@) = (Asqrt3)/(2) = (80sqrt3)/(2) = 40sqrt3N `
