Answer:
<em>b. At twice the distance, the electric potential is V/2</em>
Explanation:
Electric potential
Is the amount of work needed to move a unit charge from a reference point (usually a point at infinity) without producing acceleration.
The electric potential due to a point charge q at a distance r is given by
Where K is the Coulomb's constant. If we know the electric potential at a certain distance is V, if the distance is changed to 2r, then the new potential is
It means that the electric potential is half the previous value. Correct option: b.
So here in order to find the average velocity we can say
so first we know that along the horizontal and along the inclined it moves with same time interval
so here we will have displacement in x direction as
now the average velocity in x direction will be given as
now similarly for y direction
first we will find its displacement
now the average velocity in y direction will be given as
now net velocity is given as
