Express the two forces in cartesian vector form when f1 = 250 n and f2 = 525 n. express the resultant vector as a cartesian vector. determine the magnitude and coordinate direction angles of the resultant. force f1 is rotated 45 degrees from the y axis in the x-y plane and 60 degrees up in the z direction. also, determine the coordinate direction angles of f1.

i think the answer is a, hope this is right, that would be my best guess.

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.

amplitude

hope this

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
