Q. In a region of space, suppose there exists a uniform electric field $E = 10 \hat{i} (\frac{V}{m}) .$ If a positive charge moves with a velocity $v = - 2 \hat{j}$ , its potential energy

Increases

Decreases

Does not change

Initially increases then decreases

As charge moves perpendicular to $E$ , no change in energy occurs.

Q. In a region of space, suppose there exists a uniform electric field E=10i^(mV​). If a positive charge moves with a velocity v=−2j^​, its potential energy
