given:
Let the unknown charge be q.
The charge on proton = Q = e
the distance of test charge from q = 3 nm
the distance of test charge from Q = 4.5 nm
electric field due to a point charge at a distance r is given by
As the net force on the test charge is zero, it means the net electric field due to the proton and the unknown charge is zero.
Therefore,
[answer]
therefore, the correct option is 3rd option. [answer]
