Given two vectors, one 8 units in length the other 3 units in length, explain why the maximum resultant of the two is a single vector 11 units in length and the minimum resultant of the two is a single vector 5 units in length.

Here two vectors are given of lengths

now let say the two vectors are inclined at some angle with each other

so the resultant is given as

now plug in all values

Now for maximum resultant the angle between two vectors must be ZERO degree

Now for minimum resultant the angle between two vectors must be 180 degree

yup its correct its: c) b b

no. dot product   =0 when vecs at right angles
