To determine The correct option. Explanation Write the expression for work done ( W ) . W = ( F cos θ ) s (1) Here, F is magnitude of the force, s is magnitude of the displacement, and θ is angle between the force and displacement. With regard to the current scenario, from the given Figure it can be written as, cos θ = F 1 F 2 (2) Re-write the equation (2) as follows. F 1 = F 2 cos θ (3) From the equation (3), it said that if cos θ takes positive value, then the of F 1 must be higher than F 2
