l T-Mobile 21:04 Exit A charge of +8 micro-coulombs is placed at the bottom left corner of a rectangle, a charge of -8 micro-coulombs is placed at the top left corner of a rectangle, a charge of +7 micro-coulombs is placed at the bottom right corner of a rectangle, and a charge of +7 micro-coulombs is placed at the top right corner of a rectangle. The rectangle has a height of 20.6 cm and a width of 12.8 cm. (See sketch). What is the angle of the total electric field at the middle of the left side in degrees measured counter-clockwise from the +x axis? 92 93 height qu 94 width

Answer 1

As you Know electric field due to the positive charge outwards and due to the the negative charge towards itself(negative charge).

As you know electric field due to the point charge

E=kq/r^2
