So yes, electric field strength is a vector quantity ... But are the directions opposite coz the field lines will go INTO both the alpha particle and the proton?
And this ...
force per unit charge M1
on either a stationary charge
or a positive charge
Should we write either of the two .. or should we write 'either a stationary charge or a positive charge'??
please answer my above questions
