Question

Three charges are arranged as shown in the figure below. Find the magnitude and direction of the electrostatic force on the 6.00 nC charge. Show My Work joptiona o A 8.4 nC charge is located 2.3 m from a 3.6 nC charge. Find the magnitude of the electrostatic force that one charge exerts on the other Is the force attractive or repulsive Show My Work joptonal A charged particle A exerts a force of 2.26 to the right on charged particle B when the particles are 12.9 mm apart. Particle B moves straight away from A to make the distance between them 16.4 mm. What vector force does particle B then exert on A? AN to the left Show My Work (optional In the figure below, determine the point (other than infinility) at which the total electric field is zero. m to the left of -2.5 106 C charge Show My Work (optional A small object of mass 2.40 g and charge-14 uC "floats" in a uniform electric field. What is the magnitude and direction of the electric field?

Explanation / Answer

7.

Q1 = 8.4 x 10-9 C

Q2 = 3.6 x 10-9 C

r = distance between the charges = 2.3 m

electrostatic force is given as

F = k Q1 Q2/r2

F = (9 x 109) (8.4 x 10-9) (3.6 x 10-9)/(2.3)2

F = 5.14 x 10-8 N

8.

Q1 = ?

Q2 = ?

F = force initially = 2.26 x 10-6 N

r = distance between the charges = 12.9 x 10-3 m

using the equation

F = k Q1 Q2/r2

2.26 x 10-6 = (9 x 109) Q1 Q2/(12.9 x 10-3)2

Q1 Q2 = 4.2 x 10-20 eq-1

r' = new distance = 16.4 x 10-3

F' = new force

using the equation

F' =  k Q1 Q2/r'2

using eq-1

F' = (9 x 109) (4.2 x 10-20)/(16.4 x 10-3)2

F' = 1.41 x 10-6 N
