Example What are the x- and y-components of vector in the Figure below?
(a)The magnitude of the vector is 3 m, and the angle a =

Op = (360° - a)= (360° – 45°) = 315°
Ce = (90°-B) = (90° - 37°) = 53°

Balloon a has charge q, and identical mass balloon b has charge 10q. you hang them from threads near each other. choose all of the statements with which you agree. check all that apply. a. a and b exert the same magnitude forces on each other. b. the force that a exerts on b is 10 times the force that b exerts on a. c. the angle between the thread supporting a and the vertical is < the angle between the thread supporting b and the vertical. d. the force that a exerts on b is 1/10 the force that b exerts on a.
