Two displacement vectors have magnitude 5.0 m and 7.0 m. Which of these statements is /are true?

a)When vectors are added the magnitude of the sum could be 4.0 m.

b)If the magnitude of the sum of the two vectors is 12 m, the angle between them must be 0 deg.

c)If the magnitude of the sum of the two vectors is 2 m, the angle between them must be 180 deg.

d)Only vectors of equal magnitude can be added together.

e)When these vectors are added, the magnitude of the sum could be larger than 12 m.
