Question

how much work is done to move a charge of 3 coulomb from a point at thevolts 115 to a point at 125 volts

Answer 1

Work done = Q(potential difference between the two points).
W = 3(125-115)
W = 30 J

Hope it's helpful.

Answer 2

Your question

how much work is done in moving charge of 3 coulombs from a point at 115 volts to a point at 125 volts ?

Too Easy

Your answer

Here ,

Given in the question →

• Charge = 3 C , which has to move in electric field from a point 'A'(115) to point 'B' (125) (say)

• So , Potential difference = 125 - 115 = 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.
