Four forces act on a point 150 gm SE, 300 gm due S 60" W.280 gm due W and 180 gm 60" S of E. (a) What single force wil replace the four forces? (b) What single force
(called the equilibrant) would balance the four forces? Solve algebraically,

The magnitude of the magnetic field at a certain distance from a long, straight conductor is represented by b. what is the magnitude of the magnetic field at twice the distance from the conductor? a. at twice the distance, the magnitude of the field is 4b.b. at twice the distance, the magnitude of the field is 2b.c. at twice the distance, the magnitude of the field is b/2.d. at twice the distance, the magnitude of the field is b/4.e. at twice the distance, the magnitude of the field remains equal to b.
