Q. An object with a height of 39 is placed 1.5 in front of a concave mirror with a focal length of 0.49. Find the location of the image produced by the mirror using the mirror and magnification equations.

Q. Two charges q1 = 1.1 10-8 C and q2 = -4.8q1 are placed 50 cm apart. Find the point along the straight line passing through the two charges at which the electric field is zero, as measured from q1.
