A constant magnetic field is applied perpendicular to the plane of a square, single-turn coil with each side equal to 15 cm. If the area of the coil decreases at a rate of 0.20 m2/s, an emf of 20 mV is induced in that coil
What is the strength of the magnetic field applied to the coil? A) 0.10 T B) 0.20 T C) 0.30 T D) 0.40 T E) 0.50 T
A 3.00-m rod is pivoted about its left end. A force of 7.80 N is applied perpendicular to the rod at a distance of 1.60 m from the pivot causing a ccw torque, and a force of 2.60 N is applied at the end of the rod 3.00 m from the pivot. The 2.60-N force is at an angle of 30.0o to the rod and causes a cw torque. What is the net torque about the pivot? (Take ccw as positive.)
a. 16.4 N·m b. –8.58 N·m c. 8.58 N·m d. –16.4 N·m e. 4.68 N·m
