Question
A ring of radius R carries a charge + q A test charge - q0 is released on its axis at a distance√3 R from its centre. How much kinetic energy will be acquired by the test charge when it reaches the centre of the ring :-
Options
A.
B.
C.
D.
Solution
Apply C.O.M.E.
mv2 + (-q0) 
= 0 + (-q0) 
mv2 + (-q0) = 0 + (-q0) Create a free account to view solution
