if an isolated conducting sphere has a surface charge density σ. a) If we divide the sphere into two caps, determine the electrostatic force that tends to separate them. give results as a function of the angle θ b) what will be the value of said force in the case that θ = 90° and the potential of the sphere were V=50000 volts
