What is the escape speed for an electron initially at rest on the surface of a sphere with a radius of 1.2 cm and a uniformly distributed charge of 1.8 * 10-15 C? That is what initial speed must the electron have in order to reach an infinite distance from the sphere and have zero kinetic energy when it gets there? The charge of an electron is 1.602 x 10-19 C and its mass is 9.109 10-31 kg.
Please I need help in physics 1: An electron is held at rest at a distance 2.0 cm from a negative point charge of 1.5 nC. hat is the kinetic energy of the electron (in Joules) if it has been released from rest and traveled to a point that is 8.0 cm away from the charge? k 8.988 x 10 (N m/c2) ,-8.85 x 10-12 (C2/N m ) e 1.602 x 10-19 C I nC- 109 C 1 cm-0.01 m
