A positively charged rod is brought near an electroscope. Even though the rod does not touch the electroscope, the leaf of the electroscope deflects. Below, three students discuss this demonstration. Amadeo: "There are positive charges that jump from the rod to the plate of the electroscope. Since the electroscope is now charged, the leaf moves out." "Charges don't have to move from the rod to the plate to deflect. When the rod comes close, electrons in the electroscope move toward the plate. This leaves the bottom of the electroscope positively charged, and the leaf lifts." Barun: Carmen: "Positive charges are fixed in place. When the rod is brought close to the electroscope plate, the electrons in the plate are attracted and jump to the rod. This leaves the electroscope positively charged, and the leaf lifts."

An eletrostatic paint sprayer consists of a charged metal sphere. Charged paint droplets (the sign the same as the metal sphere) are shot towards the metal sphere using a paint gun. The paint droplets repel and move towards a grounded object that needs to be painted. In the figure below, an electrostatic paint sprayer has a 0.25 m diameter metal sphere at a potential Vsphere of 23 kV that repels paint droplets onto a grounded wall. a) What charge is on the sphere? b) What charge must a 0.14 mg drop of paint have to arrive at the object with a speed of 12 ms?

See figure. All charges are positive except q3. What is the initial acceleration of q4, which has a mass of 6.50 micrograms? Recall that acceleration is a vector and should be expressed accordingly.
you have two point charges half a meter apart. the charges have values of positive 1.0 microC and negative 2.0 microC. you want to move the charges apart to twice the distance between them, determine the amount of work needed just need to make sure i understood the question correctly and i followed through with the right method my answer that i got was 18 x 10^-3N
I need help with the first two parts of the question. Thanks!
