Question

The work done in moving 4 micro coulomb charge from one point to another in an electric field is 0.012j. the potential difference between them is

Answer 1

Answer:

WD per unit charge=  $\frac{1.2*10^{-2}}{4*10^{-6}} = 3*10^3$ $V$

Answer 2

THE POTENTIAL DIFFERENCE IS 3×10³ Volt .

Given:

• 4 uC charge is move from 1.2 another in an electric field and work done is 0.012 J

To find:

• Potential difference between them ?

Calculation:

Potential difference is defined as the work done to transport a unit positive charge from one place to another in a uniform electric field.

$V = \dfrac{W}{q}$

$\implies V = \dfrac{0.012}{4 \times {10}^{ - 6} }$

$\implies V = \dfrac{12 \times {10}^{ - 3} }{4 \times {10}^{ - 6} }$

$\implies V = 3 \times {10}^{ - 3 + 6}$

$\implies V = 3 \times {10}^{ 3} \: volt$

So, the potential difference is 3 × 10³ V.
