Why are equipotential lines perpendicular to field lines

No work is required to move a charge any where

Step-by-step explanation:

since the electric field lines point radially away from the charge. they are perpendicular to the equipotential lines.

the potential is the same along each equipotential line, meaning that no work is required to move a charge anywhere along one of those lines.

answer: the answer is one of

step-by-step explanation:   we are given to write a proper fraction where the whole is divided into an even number of equal parts less than ten, and an odd number of those parts exist.

an even number less than 10 may be one of 2, 4, 6 or 8. so, the whole may be one of these four evens.

now, an odd number of these parts must exist, so the numerator must be an odd number, one of 1, 3, 5 or 7. it cannot be 9 because then the fraction will become improper.

thus, our fraction may be one of the following

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.
