Answer 2

anyone able to guide me through this question?

Answer 3

start by parameterizing the path

Answer 4

and use below crazy notation :
dr = <dx, dy>

Answer 5

F.dr = F.<dx, dy>

Answer 6

is the parametrising related to the parabla y^2 = x?

Answer 7

yes we need to parameterize the path because it has two variables but the path can be modeled using one parameter itself as x and y are dependent

Answer 8

we only parameterize the path in line integrals,
dont tough the force vector yet...
