Question

Which statement about subatomic particles is not true?
A) Protons and neutrons have the same charge
B) Protons and electrons have the opposite charhes
C) Protons and neutrons have almost the same mass
D) All of the above

Answer 1

answer : option (A) Protons and neutrons have the same charge.

explanation : Let's check all options with detail elaboration.

option (A) : Protons and neutrons have the same charge.

this is not true, because neutrons doesn't have any charge. while a proton has 1.6 × 10^-19C charge.

option (B) : Protons and electrons have the opposite charhes

this is true, because charge on each proton = +1.6 × 10^-19C whereas charge on each electron = -1.6 × 10^-19C

option (C): Protons and neutrons have almost the same mass.

this is also true statement, because mass of proton = 1.6726 × 10^-27 kg and mass of neutron =1.6749 × 10^-27 kg.

it seems mass of proton is almost same of mass of neutron.

hence, only option (A) is not true so, option (A) is correct choice.

Answer 2

hey mate your answer is

proton and neutron have the same charge
