the max and minimum resultant is achieved when the angle is 0 and 180
so the larger vector is (17+7)/2 = 12n
and the least vector is (17-7)/2 = 5n
when the resultant is 13 the angle is
cos inverse {( 169 - 144 - 25)/120}
= 90 degree
so the larger vector is (17+7)/2 = 12n
and the least vector is (17-7)/2 = 5n
when the resultant is 13 the angle is
cos inverse {( 169 - 144 - 25)/120}
= 90 degree
