Q. 8

A force F = a + b

Class 11th HC Verma - Concepts of Physics Part 1 8. Work and Energy

Answer :

Given the force displacement linear relation is F = a+bx Now the body moves in +ve X direction from x=0 to x=d So, at x=0 we have F=a, which we get from the linear relation and also at x=d we have = a+bd

Now by taking the average of forces at both the positions we get Avg force = (F+)/2
