Explanation / Answer

solving first 5 Question

1

Let A is positive ,then B will be positive and C will be negative

SO we can see A and C will attract each other

option (A) is correct

2.option (B) is false ,It is not a straight line

option (B) is answer

3.Net chagre=(Q1+Q2)/2=(5-9)/2=-2 q

4 Ground the conductor

option(A) is answer

5.Will move toward higher potential

option C
