Answer:

Given :-

The point of 20 MJ work is done in moving a change of 100 uc across two points in an electric circuit.

To Find :-

What is the potential difference between the two points.

Formula Used :-

\clubsuit♣ Potential Difference Formula :

\begin{gathered}\mapsto \sf\boxed{\bold{\pink{V =\: \dfrac{W}{Q}}}}\\\end{gathered}

V=

Q

W

where,

V = Potential Difference

W = Work Done

Q = Charge

Solution :-

First, we have to change work done MJ to J :

\implies \sf Work\: Done =\: 20\: MJ⟹WorkDone=20MJ

\begin{gathered}\implies \sf Work\: Done =\: 20 \times 1000000\: J\: \: \small\bigg\lgroup \sf\bold{\pink{1\: MJ =\: 10^6\: or\: 1000000\: J}}\bigg\rgroup\\\end{gathered}

⟹WorkDone=20×1000000J

1MJ=10

6

or1000000J

\begin{gathered}\implies \sf Work\: Done =\: 20000000\: J\\\end{gathered}

⟹WorkDone=20000000J

\implies \sf \bold{\purple{Work\: Done =\: 2 \times 10^7\: J}}⟹WorkDone=2×10

7

J

Again, we have to change charge uc to C :

\implies \sf Charge =\: 100\: uc⟹Charge=100uc

\begin{gathered}\implies \sf Charge =\: 100 \times 0.000001\: C\: \small\bigg\lgroup \sf\bold{\pink{1\: uc =\: 0.000001\: or\: 10^{- 6}\: C}}\bigg\rgroup\\\end{gathered}

⟹Charge=100×0.000001C

1uc=0.000001or10

−6

C

\implies \sf Charge =\: 0.0001\: C⟹Charge=0.0001C

\implies \sf\bold{\purple{ Charge =\: 10^{- 4}\: C}}⟹Charge=10

−4

C

Now, we have to find the potential difference :

Given :

Work Done (W) = 2 × 10⁷ J

Charge (Q) = 10-⁴ C

According to the question by using the formula we get,

\longrightarrow \sf V =\: \dfrac{2 \times 10^7}{10^{- 4}}⟶V=

10

−4

2×10

7

\longrightarrow \sf V =\: 2 \times 10^3⟶V=2×10

3

\longrightarrow \sf\bold{\red{V =\: 2000\: V}}⟶V=2000V

{\small{\bold{\underline{\therefore\: The\: potential\: difference\: between\: the\: points\: is\: 2000\: V\: .}}}}

∴Thepotentialdifferencebetweenthepointsis2000V.
