Question

Find electric potential at 10 cm from a) electron. b) proton. c) neutron ?​

Answer 1

To find:

Electrostatic potential at 10 cm from

• Electron

• Proton

• Neutron

Calculation:

For electron:

$\therefore \: V = \dfrac{1}{4\pi \epsilon_{0}} (\dfrac{q}{r} )$

$= > \: V = 9 \times {10}^{9} (\dfrac{ - 1.6 \times {10}^{ - 19} }{0.1} )$

$= > \: V = - 14.4 \times {10}^{10} \times {10}^{ - 19}$

$\boxed{ = > \: V = - 14.4 \times {10}^{ - 9} \: volt}$

For proton:

$\therefore \: V = \dfrac{1}{4\pi \epsilon_{0}} (\dfrac{q}{r} )$

$= > \: V = 9 \times {10}^{9} (\dfrac{ 1.6 \times {10}^{ - 19} }{0.1} )$

$= > \: V = 14.4 \times {10}^{10} \times {10}^{ - 19}$

$\boxed{ = > \: V = 14.4 \times {10}^{ - 9} \: volt}$

For neutron:

$\therefore \: V = \dfrac{1}{4\pi \epsilon_{0}} (\dfrac{q}{r} )$

$= > \: V = \dfrac{1}{4\pi \epsilon_{0}} (\dfrac{0}{r} )$

$\boxed{ = > \: V = 0 \: volt}$
