Answer:

at t = 0.001 we have

at t = 0.01

at t = infinity

Explanation:
As we know that they are in series so the voltage across all three will be sum of all individual voltages
so it is given as

now we will have

now we have

So we will have

at t = 0 we have
q = 0

also we know that
at t = 0 i = 0




so we have

at t = 0.001 we have

at t = 0.01

at t = infinity

Answer:
Part a)

Part b)

Explanation:
Part a)
As we know that initially the position vector is r
then the same magnitude position vector is rotated by 40 degree angle
so displacement magnitude is the magnitude of change in position vector
so it is given as




Part b)
now we need to find the direction of the displacement vector
so let say it makes an angle with x axis so we have
