A force F is related to the position of a particle by the relation F=(10x2)N. The work done by the force when the particle moves from x = 2 m to x = 4 m is :
As we know that,
Given F = 10x2
And x =2 to x =4.
Work done is based on the integration of force with distance as follows:
W=∫42Fdx
= ∫4210x2dx
= [(10x3)3]42
= 103[43−23)]
= 103×56
= 5603J
Thus option C is correct.
