you have two pendulums with cords that are exactly the same length. one is on earth (with an acceleration due to gravity of 9.81
olga55 [171]
From  T = 2π√(l/g).

Since the lengths are the same, so that is a constant.

T α 1/√g

So the period T is inversely proportional to the square root of gravity g.

So the one with a bigger gravity g would have a shorter period

and

the one with smaller gravity g would have a longer period.

Therefore the period on the Moon with gravity of 1.63 m/s² would be longer period than that on the Earth with gravity of 9.81 m/s²

For a point charge, how does the potential vary with distance from the point charge, r?.
Sladkaya [172]

For a point charge, The potential varies inversely with distance from the point charge r, that is Potential V ∝ \frac{1}{r}

A point charge is defined as a charge that neither has mass nor volume, that is it exists as a single point.

The point charge with respect to the electric potential should be expressed in

V = KQ/r

Here we can say that the electric potential should be varied oppositely to the distance

Electric potential is defined as the amount of work needed to bring a charge from infinity to a certain place in opposition to electrostatic force. Only when there is a potential gradient at the conductor's ends do electrons travel across it.
