In the figure particles 2 and 4, of charge -e, are fixed in place on a y axis, at y₂ = -8.38 cm and y4 = 4.19 cm. Particles 1 and 3, of charge - e, can be moved along the x axis. Particle 5, of charge +e, is fixed at the origin. Initially particle 1 is at x₁ = -8.38 cm and particle 3 is at x3 = 8.38 cm. (a) To what x value must particle 1 be moved to rotate the direction of the net electric force Fnet on particle 5 by 30* (b) With particle 1 fixed at its new position, to what x value must you move particle 3 to rotate back to its original counterclockwise? direction?

What is a dielectric material? Give two examples.

Q5/ An electric field of 8.5 x 105 V/m is desired between two parallel plates each of (7 cm x 8 cm) and separated by 3.5 mm of air. What charge must be on each plate? What is the value of energy stored in the capacitor? A dielectric insulator has been inserted between the two plates.What is the value of K for this insulator in order to double the charge on the plates?

Required information Three point charges are fixed in place in a right triangle, as shown in the figure. +0.800 μC L. -0.600μ C +1.00μC where y = 8.20 cm and z= 9.20 cm. What is the magnitude of the electric force on the +1.00-μC charge due to the other two charges? N
