Question

When charge of $3$ coulomb is placed in a Uniform electric field, it experiences a force of $3000$ newton, within this field, potential difference between two points separated by a distance of $1\text{cm}$ is (in volt)

Answer 1

Step 1, Given data

Charge = 3 C

Force = 3000 N

Distance = 1 cm = 0.01 m

Step 2, Finding an electric field

We know,

The electric force is given as

$F=q\times E$

Putting all the values

$3000=3\times E$

Or, E = 1000 V/m

Step 3, Finding the potential difference

We also know that potential difference is given as

$V=E\times d$

Putting all the values

$V=10000\times 0.01=10V$

Hence the potential difference is 10 V
