how much work is done in moving charge of 3 coulombs from a point at 38 volts to a point at 48 volts ?

Too Easy

Your answer

Here

Given in the question →

• Charge = 3 C , which has to move in electric field from a point 'A'(38) to point 'B' (48) (say)

• So , Potential difference = 48 - 38 = 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.

Answer 2

Answer: The total work done is 30 Joules.

Explanation:

Potential Difference V = 48V - 38V = 10V

Quantity of charge Q = 3C

We know that, V = W/Q

So, Work done W = V*Q

                              = 10V * 3C

                              = 30J
