Suppose we have two positively charged particles a distance of 2 m apart from each other. Particle 1 has a charge of 6 C and particle 2 has a charge of 1.3 x 10^3 C. What amount of
electrostatic force exists between these two particles?
1.7 x 10^13 N
7.02 x 10^13 N
2.6 x 10^3 N

Suppose a diode consists of a cylindrical cathode with a radius of 6.200×10^−2 cm , mounted coaxially within a cylindrical anode with a radius of 0.5580 cm . the potential difference between the anode and cathode is 260 v . an electron leaves the surface of the cathode with zero initial speed (v initial=0). find its speed vfinal when it strikes the anode.
