# The force on an electron kept in an electric field in a particular direction is F. What will be the magnitude and direction of the force experienced by a proton kept at the same point in the filed ? Mass of the proton is about $1836$ times the mass of the electron

Solution :
Force on an electron is $Fe =eE$
$F_e$ = Force vector acting on the electron
$e$ charge on the electron
Force experienced by proton having same magnitude of change but is of opposite nature,
Force will be in opposite direction to that of force on electron .
(ie) $F_P$(force on proton) = $-F_e$
The electrostatic forces depends only upon the charges and hot on the masses.
