1) A Q1 = + 4.0 nC point charge and a Q1 = - 3.0 nC point charge are 6 cm apart on the x-axis. Find the point on the x -axis where the electric field...
1) A Q1 = + 4.0 nC point charge and a Q1 = - 3.0 nC point charge are 6 cm apart on the x-axis.
Find the point on the x -axis where the electric field is zero.
Hint: Draw Electric vectors for both charges at a point between the two charge, and also at a point outside of the two charges on the right side of Q2 and on the left side of Q1
2) What is the net force on q 1 . The three charges are at the three vertices of an equilateral triangle ?( all angles are 60degrees)
q 1 = - 1.0 nC
q 2 = - 2.0 nC
q 3 = + 3.0 nC
Equilateral side of the triangle = 4 cm.
Hint: Calculate forces acting on q1
You must show all the forces acting on q1. on the figure. Resolve each force in X and Y direction.
The find the F net in X and F net in Y. Use Pythagorean theorem the find the Net force.
