2. An average human weighs about 650 N. If each of two average humans could carry 1.0 C ofexcess charge, one positive and one negative, how far apart would they have to be for theelectric attraction between them to equal their 650N weight?     please explain me step by step please

A positive charge q = 1.5 C moves from A to B as shown. At point A, it has kinetic energy 15 J. What is its kinetic energy at point B, in Joules? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.

A conducting sphere is intially neutally charged. Its grounded, meaning the sphere has a direct path to earth ground. Which of the following describes the flow of electrons when a positvely charged rod is broght near the sphere? a. Electrons flow within the sphere but do not go into or out of the ground. b. Electrons flow out of the ground and into the sphere. c. Electrons flow out of the sphere and into the ground. d. There is no flow of electrons.

1. Two conducting spheres are separated by 0.550 m, measured from center-to- center. The radii of the spheres are equal and much less than the separation distance. There is an attractive force between the spheres of 0.105 N. A thin wire is then connected between the two spheres until electrostatic equilibrium is achieved. The wire is then disconnected and the spheres now repel each other with a force of 0.040 N. Determine the charges that were on the spheres before they were connected together.

This question has multiple parts. Work all the parts to get the most points. Use Coulomb's law, Q1Q2 V = 4TEOT Q1Q2 = 2.31 x 1019 J. nm to calculate the energy of interaction for the following two arrangements of charges, each having a magnitude equal to the electron charge. (The negative sign of the energy of interaction indicates an attractive force.) 5 x 10-10 m -10 a 5 x 10 Energy = J 5 x 10-10 5 x 10-10 m 5 x 10-10 m 5 x 10-10 m (b (Charges are located at square vertices.)

1. The magnitude of an electric field became 3.0 x 106 N/C or greater, so that electrical breakdown and thus sparking could occur. 2. The energy of a spark was 150 mJ or greater so that it could ignite the powder explosively. Let us check for the first condition in the powder flow through the plastic pipes. Suppose a stream of negatively charged powder was blown through a cylindrical pipe of radius R = 5.0 cm. Assume that the powder and its charge were spread uniformly through the pipe with a volume charge density p. a. Using Gauss' law, find an expression for the magnitude of the electric field E in the pipe as a function of radial distance r from the pipe center. b. Does E increase or decrease with increasing r? c. Is E directed radially inward or outward? d. For p = 1.1 x 10³ C/m³ (a typical value at the factory), find the maximum E and determine where that maximum field occurs. e. Could sparking occur, and if so, where? From the answer to part (a) of the problem, f. Find an…

Suppose you have a glass rod with a 0.68 μC charge and a polyester cloth with a -0.61μC charge, which are 13 cm apart.   What is the magnitude of the attractive force between them (in N), using the approximation that they act like point charges?
