Two long parallel wires 15 cm apart carry currents of 5.0 A and 8.0 A in the same direction. Is there any point between the two wires where the magnetic field is zero?
 a. yes, midway between the wires
  c. no
  b. yes, 9.2 cm from the 5 A wire
  d. yes, 5.8 cm from the 5 A wire

Question 2

A pendulum on the Earth has a period T. The acceleration due to gravity on Mars is less than that on the Earth, and the acceleration due to gravity on the Moon is even less. Where would the period of an identical pendulum be the least?
 a. on the Earth
  b. on the Moon
  c. on Mars
  d. The period of a pendulum would be the same on the Earth, Moon, and Mars since the period depends on the pendulum's length which is the same for identical pendula.
