Two mirrors are arranged as shown in the drawing (left, below).  Light is incident from the right on the first mirror at an angle of 70°.  The light reflects toward the second mirror and is reflected at angle θ.  Determine the angle θ.

A small bird of mass m is sitting on a perch of mass 7 g, which is supported by a magnetic force. The perch is 10 cm long and contains a wire carrying a current of 2.0 A. The perch is oriented at right angles to a uniform magnetic field of 0.9 T that is strong enough to support the perch and the bird. What is the mass of the bird?

A juicer has a rectangular coil of dimension [W] m by [L] m.  The coil is oriented such that its surface makes an angle of 30 degrees with the electric field.  The strength of the field is [E] N/C. Find the electric flux in N.m2/C passing through the coil. [Round off to the whole number]

Three equal point charges of -1.2 

The electric field at a point 2.0 cm from a small charged object has a strength of E=160,000 N/C and is directed away from the charge. What is the object’s charge?

A charge +5
