If a man pulls a trolly by applying force of 50N and trolly is displaced 30m. What is work done?
A. 1500J
B. 150J
C. 15000J
D. 15J
Answer: Option A
Solution (By Examveda Team)
To calculate the work done by the man in pulling the trolley, we'll use the formula:Work (W) = Force (F) * Displacement (d) * cos(θ)Where:
F = Force applied (50N)d = Displacement (30m)θ = Angle between the direction of force and the direction of displacement (assuming the force is applied in the direction of displacement, so cos(θ) = 1)Plugging the given values into the formula:
W = 50N * 30m * 1W = 1500JTherefore, the correct answer is Option A: 1500J.

If we look at the definition of work which,, = w= Fscos∆(theeta)
Given = f = 50 Netwon
S= 30 m
And pulls at an angle of 90°.....
So work = FSCoS ∆
W = 50×30× O ( cos 90° = zero)
W = O
