Chapter 20.2, Problem 11PP
To determine

To Draw: Diagram of the situation.

To Find: The net force on A.

Expert Solution & Answer
Check Mark

Explanation of Solution

Given:

Charge on A, qA=+6.00μC

Charge on B, qB=+3.00μC

Charge on C, qC=+1.5μC

Distance between charge A and B, dAB=4.0cm=0.04 m

Distance between charge A and C, dAC=3.0cm =0.03 m

Formula Used:

Electrostatic force between two charges:

  F12=kq1q2d2

Here, k is the Coulomb’s constant, q1 and q2 are the charges and dis the distance between them.

Calculations:

  Glencoe Physics: Principles and Problems, Student Edition, Chapter 20.2, Problem 11PP

Force between A and B:

FAB=kqAqBdAB=(9×109)(6.0×106)(3×106)0.042=1.0×102N

Force between A and C:

FAC=kqAqCdAC  =(9×109)(6.0×106)(1.5×106)0.032=9.0×101N

Both the forces repel. The net force on A due B and C:

  Fnet=FAB2+FAc2=(1.0×102)2+(9.0×101)2=130N

Angle above the negative horizontal axis:

  θ=tan1(FACFAB)=tan1(9.0×1011.0×102)=42°

Angle from the positive horizontal axis: 180°42°=138° .
