Question

How much work done in moving and charge of 3 coulombs from a point at 118 V to
a point at 128 volt?

Answer 1

Answer:

Hey!

We know that potential difference = Work done/Charge moved.

In this case, V = 230 V and V2 = 240 V. The mount off charge moved = 5 C.

Thus, the potential difference = v2-V1 = 230-240 = 10 V

Therefore, Work done = Potential difference * Charge moved.

That is, 10 * 5 = 50 Joules.

Hence, the work done in moving a charge of 5 coulombs from a point at 230 volts to another point at 240 volts is 50 J.

hope it will be helpful ✌️

Your question

how much work is done in moving charge of 3 coulombs from a point at 118 volts to a point at 128 volts ?

Too Easy

Your answer

Here ,

Given in the question →

• Charge = 3 C , which has to move in electric field from a point 'A'(118) to point 'B' (128) (say)

• So , Potential difference = 128 - 118 = 10 V

• To Calculate Work done (W) = ?

We use the Formula ,

• Work done = Total charge x potential difference

• W = Q ( total ) x V

Here ,

• Q = Total charge = Given = 3 C

And ,

• V = Potential difference = 10 V

So the word done in moving the charge from A to B will be ,

• W = 3 x 10

• W = 30 joules

Work done = 30 joules.
