TRUE OR FALSE- I WILL GIVE QUICK RATING! The lines in the figure below show the equipotential contours in the plane of three point charges, Q1, Q2, and Q3. Note that these are point charges (one is not bigger in size than the others; they're points). That means that the potential goes to infinity as you approach them. We've cut off the contours at plus and minus 7kV. The white space is where the potential is greater or less than that. The values of the equipotential lines are in kV, and we labeled the +1, 0, and -1 kV contours. The positions of the charges are also labeled.
a)Charge Q3 is the largest negative charge.
b)The electric field E at 'a' is stronger than at 'g'.

If a small sphere with charge 2 nC and mass of 20 g is held next to the positive plate, what is the force on that sphere? What will the acceleration of the sphere be? how long will it take to reach the other plate? What will its speed be when it reaches the other plate?arrow_forward
