The direction would be towards the sphere with the charge of -6 x 10^-7 C, right? So if the potentials are the same I just use the equation kQ1/r1 = kQ2/r2? I know k and the radii. What would i put in for the Q's?

Homework Statement Constant in Coulomb's Law: k = 9 x 10^9 Nm^2/C^2 1) Two metal spheres are each given a charge as shown below. They are initially placed 30 cm from one another (center-to-center distance). (Qa = -6 x 10^-7 C) (Qb = -4 x 10^-7 C) (Ra = 5cm) (Rb=2cm). A) For purposes of...

great, I see. thank you so much.

so is friction equal to weight?

Homework Statement In order to hold a book of mass m stationary against a wall, you must push horizontally with a force of at least P. a. make a force diagram and find the coefficient of static friction b. calculate the coefficient of static friction for the wall and book when at least a...
