Three-point charges are arranged on a line. Charge q3 = +5.00nC and is at the origin. Charge q2 = -3.00 nC and is at x = 5.00 cm . Charge q1 is at x = 2.50 cm. What is q1 (magnitude and sign) if the net force on q3 is zero?

Explanation:

Given

Charge is placed at origin

Charge is placed at

Charge is Placed at

charge must be positive so as to balance the force on charge

Force on due to is

here

Force on due to is

false.

explanation:

this statement is false. after falling for 5 seconds, its speed will not be 100 m/s.
