The frame of reference is the rotating earth underneath the flight path of the plane, the rate of rotation of the earth is 1036 miles per hour, meaning that the pilot has to compensate this fact when landing the aircraft.

How much work w is done by the electrostatic force on the moving point charge?

V125BC [204]

As we know that electrostatic force is a conservative force

so we can say by the condition of conservative force

$F_c = -\frac{dU}{dr}$

here we can rearrange the above equation as

$dU = - F_c.dr$

now integrate both sides

$\int dU = - \int F_c . dr$

Now we know by the definition of work done by a force is given by

$W = \int F.dr$

now work done by conservative force is given as

$W_c = \int F_c . dr$

Now from above work done by electric field to move charge from one point to other is given as

$W_{EF} = \int F_{e}.dr = - \int dU$

so here work done is given as

$W_{EF} = U_i - U_f$

so change in potential energy is given by work done
