  Question

  
• Answer:

  2 (a), Force per unit charge

  (i), Direction

  (ii), E = Q/ 4pi * E0 * r^2 therefore E has a inverse square relationship with r so answer = 2.0*10^5

  Question:

  
• Answer

  E = Qq/4pi*E0*r^2

  9.21 * 10^-8

  F = -GMm/r^2

  4.06*10^-47

  so answer = 2.3 * 10^39
