Given, work done by both person is same,
WA=WB Direction of first force with displacement,
θ1 = 45°
Direction of first force with displacement,
θ2 = 60°
Ratio of force applied by person A to force applied by person B is
FA:FB=1:√x.
Work done by both person is same,
WA=WB= ⇒FAdcosθ1=FBdcosθ2 (∵ distance is same for both = d)
== ⇒== ⇒== ⇒x=2 Thus, the value of x is 2.
