# An electricity and magnetism problem by Harshvardhan Mehta

In the above diagram shown(please make it yourself according to additional information as i am not able to upload the diagram), the charge +Q is fixed. Another charge +2q and mass M is projected from a distance R from the fixed charge. Minimum separation between the two charges if the velocity becomes $$\frac{1}{\sqrt{3}}$$ times of the projected velocity, at this moment is (Assume gravity to be absent).

Additional Information: The projected velocity makes an angle of 30 degree with the line joining two charges and at charge +2q
