Question

1- Change in electric field when you move from one point of equipotential line to any other point on the same line is …… a. infinite b. depends upon distance c. zero d. unpredictable

2- Which instrument (ammeter or voltmeter) does m1, m2 and m3 represents for? explain

Answer 1

i am understanding problem number one so that i am solving this..

1-- equipotential line means potential at line at every point will be same that means if we move along equipotential line we are at same potential and in that line the field will be always perpendicular that means if we move on same line the electric field not changed because it is again perpendicular ...hence change in field will be 0 . (option c is the answer)

i am not getting your second question....so again ask by recheking it..

thanks...
