Question

Object A, which has been charged to + 10 nC , is at the origin. Object B, which has been charged to 20 nC , is at (x,y)=(0.0cm,2.0cm).

1.) What is the magniude of the electric force on object A?

2.) What is the magnitude of the electric force on B?

3.) What is the direction of the force on object A?

a. postive x-axis

b. positive y-axis

c. negative x-axis

d. negative y-axis

4.) What is the direction of the elecrtic force on object B?

a. positive x-axis

b. postive y-axis

c. negative x-axis

d. negative y-axis

a) as the force between two charged particles is given as

F = k * q1*q2/d^2

force acting on particle A = 9*10^9 * 10 *10^-9 * 20 *10^-9/0.02^2

force acting on particle A = 4.5 *10^-3 N

the force acting on particle A is 4.5 *10^-3 N

according to Netwon's third law of motion

force acting on particle B = force acting on particle A

force acting on particle B = 4.5 *10^-3 N

the force acting on particle B is 4.5 *10^-3 N

as oposite charges attract each other,

direction of force on A is (b) positive y - axis

as oposite charges attract each other,

direction of force on B is (c) negative y - axis
