Explanation / Answer

1)electric field lines are drawn from positive charges to negative charges

2)false (it is the same potential difference)

3)true (it is an imaginary surface)

4)The electric field is always perpendicular to the equipotential surface

5 )because number of equipotential lines gives net flus across the surface

6)1

7)

8) more information needed

9)it depends on the configuration of the charge

4)
