the ratio of electrostatic force FE to gravitat... - JAMB Physics 2001 Question
the ratio of electrostatic force FE to gravitational force FG between two protons each of charge e and mass m, at a distance d is
A
e/4πԐoGm
B
e2/Gm2
C
Gm2/4πԐoe2
D
e2/4πԐoeGm2
correct option: d
Electrostatic force = FE = e2/4λEod2
Gravitational force = FG = GM2/d2
Gravitational force = FG = GM2/d2
