Question

A helium -4 nucleus conains two neutrons and two protons. The mean separation between the orotons is 3*10^-15 m . Calculate the elecric force experienced by each proton .
@amistre64

Answer 1

Coulomb's law

Answer 2

what charge I should use

Answer 3

the charge on a proton

Answer 4

helium 4 nuclues shall i time it by 4 * charge on a proton ?

Answer 5

no, you want the force between two protons, each proton has the same charge

Answer 6

look up coulomb's law

Answer 7

umm ,
well
I know what columbs law is
im just confused about the value of Q the charge

is it 2* Q ?

Answer 8

2* Q sqaured ?

Answer 9

is there a factor of 2 in coulomb's law ? No

Answer 10

charge on each proton is 2(1.6*10^-19) right ?

Answer 11

wrong

Answer 12

can you guide me please ?

Answer 13

the charge on a proton is equal in magnitude to the charge on an electron
