Find the orthogonal decomposition of vector b = 8, 0, 0 with respect to vector a = 3, −5, 0 . (your instructors prefer angle bracket notation < > for vectors.)

i think its c if i'm wrong

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

the answer is 100. i just did this lesson and got a 100% on it. : )
