Apositive point charge on a 2-d plane starts at the position (2 cm, 7 cm). it moves along an equipotential line to the position (10 cm, 7 cm). the plane is oriented parallel to a
uniform electric field of 120 n/c. how much work does the electric field do in this scenario? (answer in joules, j. you do not need to type the units, only the number.)

W = 0

Explanation:

given data:

starting position is ( 2cm , 7 cm)

ending position is  (10 cm, 7 cm)

we know thta work done is given as

here , q is particle charge

is change in potential

as we know that intial and final position are having uniform eleectric potential, therefore it have same potential i.e. V_1 = V_2, thus

one more reason of being work done equal to zero is,

Since the distance covered by the item and the direction of motion is always perpendicular to each other during the round journey, no work is therefore carried out.

W = 0

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
