ANSWER THE FOLLOWING QUESTION AND DRAW DIAGRAM FOR EACH PART OFQUESTION

Q1(A).Two point charges are located on the x axis. The first isa charge +Q at x = a. The second is an unknown charge located at x= -3a. The net electric field these charges produce at the originhas a magnitude of 2keQ/a2. What are the two possible values of theunknown charge?

Q1(B)In Fig. 3, particle 1 of charge +1 μC and particle 2 ofcharge -3.0 μC are held at
separation L =10.0 cm on an x axis. If particle 3 of unknown chargeq3 is to be located such that the net
electrostatic force on it from particles 1 and 2 is zero, what mustbe the (a) x and (b) y coordinates of
particle 3?

Q1(C)In Fig. 2, two identical, electrically isolated conductingspheres A and B are separated
by a (center-to-center) distance ‘a’ that is large compared to thespheres. Sphere A has a positive charge
of ∆Q, and sphere B is electrically neutral. Initially, there is noelectrostatic force between the spheres.
(The large separation means there is no induced charge.)
(a) Suppose the spheres are connected for a moment by a conductingwire. The wire is
thin enough so that any net charge on it is negligible. What is theelectrostatic force
between the spheres after the wire is removed?
(b) Suppose sphere A is grounded momentarily, and then the groundconnection is
removed. What now is the electrostatic force between thespheres?

the question on its own don't have any figures pleasedo make diagrams where necessary for better understanding ofanswers
