Question

Calculate the work done in moving a charge of 5c from a point at a potential of 210volts to another point at 240volts

Answer 1

Given : Moving charge is 5C, Initial velocity is 210V and Final velocity is 240V

　

To find : What is the work done.

　

☯ Solution :

★ Work done = Charge × Potential difference.

　

Concept :

• To use the above formula, first we have to find what is the Potential difference.

　

• To find potential difference we have to find the difference between (Final velocity - Initial velocity).

　

Calculations :

$:\implies\sf{Potential \: difference = (240 - 210)}$

　

$:\implies{\underline{\boxed{\sf{Potential \: difference = 30}}}}$

　

Substuting the above value :

$:\implies\sf{Work \: done = 5 \times 30}$

　

$:\implies{\underline{\boxed{\sf{Work \: done = 150 \: Joule}}}}$
