Answer 1

Q8) Option B is correct

Since, both charges are of the same sign they'll exert an electric field force which is REPULSIVE in nature. Since one charge is fixed, therefore the other will accelerate away from it .

Q9) Option B is correct

The definition of current is given by that Current is the rate of change of charge flow over a cross sectional area of conductor over time.

I.e.   I=Q/T
