Question

Work needed to move a charge of 2C from point A to point B is 10 joule. The potential difference between A and B is

Answer 1

Answer:

5V.

Explanation:

Here is your answer....

By using the formula ,

W= V× q

(W = work done

V= potential difference

Q= charge)

:- V= W/q =======> 10 joule/ 2C ====> 5J/C

(Or) 5V.

Hope this helps you a little!!!!!

Answer 2

$\red{\mid{\underline{\overline{\textbf{Answer}}}\mid}}$

Work done = 5J

$\red{\mid{\underline{\overline{\textbf{explanation}}}\mid}}$

Work is said to be done when a force is applied on a body and the body undergoes some displacement.

S.I unit of work is Joules.

In field of electricity the work done in moving charges is defined as the product of potential difference between two points and the charge . It is defined by the expression :

$\bigstar \orange{\mid{\underline{\overline{\textbf{w = v×Q}}}\mid}}$

It is given that :

Charge = 2 Coulomb

Work needed = 10J

Potential difference between points = ?

In this question we have been given that work which is done on 2C charge to move it from point A to point B, The potential difference between both points is not known, we have to calculate them.

Now, after inputting the known values in the expression we get :

$10j = v \times 2 \\ v = \frac{10}{2} \\ \\ v = 5joules$

Thus the potential difference is of 5 Joules or we can say 5Volts.
