hold in your hand a block of material with 3 x 10^ 27 protons, 3.4 x * 30 points 10^27 neutrons, and 3.1 x 10^27 electrons. Given the mass of a protons and neutrons is about 1.67 x 10^-27 kg and the mass of an electron is 9.1 × 10^-31kg. a). Determine the mass of the block, and b) Determine the charge on the block? (Recall the charge on an electron is -1.6 x 10^-19 C and the charge on a prot

The figure below shows three positively charged particles at three corners of a rectangle. The particle at upper left has a charge q1 = 4.00 nC, the one at the lower left has a charge of q2 = 5.00 nC,and the one at lower right has a charge q3 = 6.00 nC. The rectangle's horizontal side has length x = 5.00 cm and its vertical side has length y = 3.50 cm. Three positive charges lie at three of the corners of a rectangle of horizontal side length x and vertical side length y < x. An charge labeled q1 is at the upper left corner. A charge labeled q2 is at the lower left corner. A charge labeled q3 is at the lower right corner. (a)What is the electric potential (in V) at the upper-right corner of the rectangle? (Assume the zero of electric potential is at infinity.) ______V (b)What would be the potential (in V) at the upper-right corner if the charge q2 at lower left was−5.00 nC instead? _____V

On a very unrealistically staticky day, Zoey decides to try to hold up the weight of her body by grabbing onto a balloon she rubbed on her head. She rubs it on her head and then holds it up to the ceiling and lets the force of static electricity between the balloon and the ceiling hold her up. If Zoey weighs 700N and the charge on the balloon is 1.5 x 10-9 C and the balloon is 4.0 x 10 3 m away from the ceiling's charge, then what must the charge on the ceiling be to be able to create a force of electricity equal to Zoey's weight?

Four identical charged particles (q = +10.7 μC) are located on the corners of a rectangle as shown in the figure below. The dimensions of the rectangle are L = 63.6 cm and W = 14.5 cm. 9 9 W L (a) Calculate the magnitude of the total electric force exerted on the charge at the lower left corner by the other three charges. N (b) Calculate the direction of the total electric force exerted on the charge at the lower left corner by the other three charges. ° (counterclockwise from the +x-axis) Need Help? Read It
