Which is the work required to move a charge? electric field electric field line electric potential electric potential energy

The correct answer is electric potential.

Explanation:

Electric potential is the amount of work done in bringing the unit positive charge from the reference point to the particular point.

But the charge is moved in such a way that it does not produce any acceleration.

The expression for the work

Here, q is the charge and V is the potential.

Therefore, electric potential is the work required to move a charge.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
