Question

how much work is done in moving a charge of 4 coulomb in an electric field from a point A at 12V to 24V​

Answer 1

Explanation:

pAB=>230-220

=10v

now

workdone in moving the charge of 4coulomb

given by the formula

v=work done /charge

10v=work/4c

hence , the total work done=>40joule

plz like me

Your question

how much work is done in moving a charge of 4 coulomb in an electric field from a point A at 12V

to 24V ?

• Too Easy

Your answer

Here ,

Given in the question →

Charge = 4 C , which has to move in electric field from a point 'A' to point (say) 'B'

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 = 4 C

And ,

• V = Potential difference = ( 24 - 12 ) V
• = 12 V

So the word done in moving the charge from A ( 24V ) to B ( 12 V ) will be ,

• W = 4 x 12
• W = 48 joules

Work done = 48 joules.
