PHSX 115:18CH-Electric Charge and Electric Field (ICP-blank) Team Date: In-class problems 3. A balloon has a net charge of -9.6 x 10-16C. How many excess protons or electrons does the balloon have?
A negatively charged oil drop whose mass is 10-15 kg and
whose charge is -6.4 10-19 Coulombs remains stationary under the
influence of the Earth’s gravitational field and a uniform external
electric field made by two oppositely-charged parallel plates (see
diagram below). Ignore the influence of Earth’s electric field on
the oil drop.
Determine the magnitude and direction of the net
electric field created by the plates (not the electric field of the
oil drop !). Explain completely how you...
A0.00275 kg air-inflated balloon is given an excess negative charge q-3.25 x 10-8 C by rubbing it with a blanket. It is found that a charged rod can be held above the balloon at a distance of d0.0540 m to make the balloon float. In order for this to occur, what polarity of charge must the rod possess? O negative O positive O neutral O proton How much charge q2 does the rod have? Model the balloon and rod as...
Chapter 19, Problem 34 GO A positive point charge (q-+5.80 x 10-8 C) is surrounded by an equipotential surface A, which has a radius of r4-2.95 m. A positive test charge (90 = +3.48 x 10-11 C) moves from surface A to another equipotential surface B, which has a radius rg. The work done by the electric force as the test charge moves from surface A to surface B is WAB--9.11 x 10-9 J. Find ra

A proton has a positive electric charge e = 1.609 times 10^-19 C. What is the electric potential energy of an electron (charge -e) at a point 5.29 times 10^-11 m from the proton? For simplicity, use k = 9.00 times 10^9 Nm^2/C^2. Three charges are spaced along the positive x axis at 1.0 cm intervals, beginning at the origin. Starting with the charge at the origin, the charges have values -4.2 mu C, + 1.3...
