Summary of
answer:-We use coulomb's law to find the
electrostatic force due to q1 and q3 on charge q2.Now we write them
in vector form so that on adding both the forces directly we will
get vector form of net force.Now on taking the magnitude of
resulting vector by analytical formula we get magnitude of net
force on q2.To find the direction of net force with positive
direction of x axis we use the formula arc tan(coefficient
of j/coefficient of i).
(d) take half of r (e) double the magnitude of one of the charges (f) take...
