Answer on Question #59521, Physics / Mechanics | Relativity |

A proton is held motionless between two horizontal metal plates 10 cm apart. What voltage

should be applied between the plates?

Solution:

= 1.67 ∙ 10−27 kg, mass of proton

= 1.6 ∙ 10−19 C, charge of proton

= 0.1 m

The gravitational force on a proton would be balanced by the electric field.

Balance of forces:

=

Therefore,

=

=

1.67 ∙ 10−27 ∙ 9.8 ∙ 0.1

1.6 ∙ 10−19 ≈ 1 ∙ 10−8

Output: 1 ∙ 10−8
