Question

a) What is the speed of the proton before it hits the surface of the sphere?

b) What is the sheets surface charge density?

a). A proton (q = 1.6x10-19, m 1.67x1027 kg) initially at rest released from infinite distance from the sphere with a radius of 0.03 m and a uniformly distributed negative charge of -5x10-13 C. Find the speed of the proton just before it hits the surface of the sphere. b). An electron (q=1.6×1019C, m = 9.1x103ikg) is shot directly away from a uniformly charged, flat, very large sheet, at -31 speed v, = 4x105 m/s. Graph (b) gives the electron's speed versus time (1pc=10-12) until it returns to the launch point. What is the sheet's surface charge density? 6. 12 -Vs t (ps) (a) (b) v (10 m/s)
