Question

Two point charges are placed at a and b at a certain distance from each other. Assuming the
field strength is positive in the direction coinciding with the positive direction of the x axis
( )
E+
b: x
(A) Charge at a is positive and at b negative
(B) Magnitude of charge at a is greater than that of charge at b
(C) Both charges at a and b are negative
(D) Magnitude of charge at b is greater than that of charge at a​

Answer 1

a) becouse a was in South magnitude

Answer 2

Answer:

The correct option is (B) Magnitude of charge at a is greater than that of charge at b.

Explanation:

• A hypothetical charge at a single point in space is known as a point charge. Even though an electron is often referred to as a point charge, its size can be determined by a length scale called the electron radius.
• As distance rises, the electric field for positive charges will decrease in a positive direction (instance 1), whereas the electric field for negative charges would grow as distance increases (case 4).
• The field will continue to decrease as a positive charge turns into a negative charge (case 2), Field will continue to increase when we go from a negative to a positive charge (case 3)
