Question

What is the potential at a distance of 5. 0 ? 10-10 m from a nucleus of charge 50e?

Answer 1

The electric potential at a distance from a nucleus of charge 50e is 144 Volts.

What is electric potential?

The potential is the work done by the test charge to move it from infinity to a particular point.

The potential is given by the relation

V = kQ / r

The distance of a point from the nucleus is 5.0 × 10⁻¹⁰ m and the charge on the nucleus is 50 e = 50 × 1.9 × 10⁻¹⁹ C.

k = 9 × 10⁹ kg-m²/s²-C²

Here, Q is the charge, r is the distance and k is the constant.

Substituting the value into the equation and solving, we get

V = 144 Volts

Thus, the potential at a distance from a nucleus of charge 50e is 144 Volts.
