Answer #1

Force applied by the q2 on q1 is F21

Force applied by the q3 on q1 is F31

Now let the distance between the q1 and q2 is d

Then the distance between the q1 and q3 = 2d

As all charges are identical i.e q1=q2=q3

The force F21 is

F21= q1*q2*k / d^2

Wheree k=1/4π\varepsilon

Now the force F31 can be written as

F31= q1*q3*k/(2d)^2= q1*q2*k/4d^2

F31= F21/4

Hence F21 > F31

F21 = force applied by q2 on q1 is at 1st rank

F31= force applied by q3 on q1 is at 2nd rank
