Question

2400 J work is done in moving a charge of 300 C. Calculate the potential.

Answer 1

Answer:

here ,

charge , q = 300 c

work , w = 2400 j

to find

potential, p

we know

p = w/q

=>

$p = \frac{2400}{300} \\ = > p = 8$

so, the potential is 8 volts.

Answer 2

Given ,

• Work done (w) = 2400 J
• Charge (q) = 300 C

We know that ,

The work done to move a unit charge from one point to another point is called potential difference

It is denoted by " v "

$\large {\boxed{ \sf{v = \frac{w}{q} }}}$

The SI unit of potential difference is " volt "

Thus ,

v = 2400/300

v = 8 volt

$\sf \therefore{\underline{The \: potential \: difference \: is \: 8 \: volt }}$
