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 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.

V is the energy (in J) required to bring the two charges from infinite distance separation to distance r (in nm).Q1 and Q2 are the charges in terms of electrons.(i.e. the constant in the above expression is 2.31×10-19 J nm electrons-2) For a group of "point" charges (e.g. ions) the total energy of interaction is the sum of the interaction energies for the individual pairs. Calculate the energy of interaction for the square arrangement of ions shown in the diagram below.

you have been given some info, use it to solve the questions highlighted in yellow. - an alpha particle has charge 2e and mass 6.64x10^(-27). - The alpa particle is shot aimed at a gold nucleus which is stationary. The gold nucleus has a charge of 79e. - Then the gold nucleus and the alpha particle are 10cm appart from eachother, the alpha particle moves at 1000m/s. a. What is the speed of the alpha particle when it is 1.00mm away from the gold nucleus? b. What is the closest distance the alpha particle can go reletive to the gold nucleus before the alpha particle rebounds ?
