Study the vector diagram.
what is the magnitude of vector k?
b
08 m
o 16 m
o 60 m
0 13001
vector l =
10 m
vector k=
vector j = 6

the electric field is a “force field” around a charged object that illustrates the direction the electric force would push an imaginary 

the answer is b, have negligible mass

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
