Question

(d) What is the amount of work done in moving a charge of 15 C between
points kept at a potential difference of 1.2 V?
(e) The diagram below shows the magnetic field lines of earth in a limited spa
The field lines are parallel and equidistant.
0
Are the magnetic field lines uniform or non-uniform?
() Where is the position of the geographic north, A or B?​

Answer 1

Answer:

Here is ur answer

Explanation:

Electric Field = E = Voltage V / displacement d

E=V/d

Also, Force F = charge Q X E

F = QE = QV/d

Fd/Q = V

Volatge or potential difference V is thus Fd/Q = W/Q

[Force times displacement Fd is just work done W]

W = VQ

So acc. your question, the work done is 15 X 1.2 = 18 Joules

Next question:

The filed lines are parallel always indicates that the magnetic field B is uniform.
