Question

What is the electric potential, in volts, due to the proton in an orbit with radius 0.530 × 10–10 m?

Answer 1

Answer : The electric potential on proton is, 27.1 V

Explanation :

To calculate the electric potential we are using the formula.

$V=\frac{1}{4\pi \epsilon_0}\frac{q}{r}$

where,

V = electric potential

q = charge on proton = $1.6\times 10^{-19}C$

r = radius = $0.530\times 10^{-10}m$

$\frac{1}{4\pi \epsilon_0}=8.99\times 10^9$

Now put all the given values in the above formula, we get:

$V=(8.99\times 10^9)\times \frac{1.6\times 10^{-19}}{0.530\times 10^{-10}}$

$V=27.1V$

Thus, the electric potential on proton is, 27.1 V
