A charge of 1.0  10-6 C is located inside a sphere, 1.25 cm from its center. What is the electric flux through the sphere due to this charge? (0 = 8.85  10-12 C2/N  m2)
 
  A) 0.028 N  m2/C
  B) 0.11 N  m2/C
  C) 8.9 N  m2/C
  D) It cannot be determined without knowing the radius of the sphere.

Question 2

Consider the motion of a 1.00-kg particle that moves with potential energy given by
  U(x) = (-2.00 Jm)/x + (4.00 Jm2)/x2. Suppose the particle is moving with a speed of 3.00 m/s when it is located at x = 1.00 m.
 
  What is the speed of the object when it is located at x = 5.00 m?
  A) 2.13 m/s B) 4.68 m/s C) 3.00 m/s D) 3.67 m/s
