Question

Three charges +4q, Q and
+q are placed on a straight
line such that Q is placed in
between
If
+4q and + q. If this
system is in equilibrium, what
should be magnitude and sign
of charge Q?​

Answer 1

Answer:

Explanation:

Using the centrifugal force conditions, the tension at the bottom can be related to the tension at the top: For a mass m = kg, the tension at the top of the circle is Ttop = Newtons. The corresponding tension at the bottom of the circle is Tbottom = Newtons.
