Question

Vector sum of 15 m, East and 9 m, West is 24 m, East. True False

Answer 1

False

Step-by-step explanation:

Because when you go through east

( +x axis ) then you go to west ( -x axis )

You will subtract -9 from +15

it's become +6

( I talk about the displacement not distance) ( West = - East )

I hope that it's a clear ") .

Answer 2

False.

Step-by-step explanation:

The sum of two vectors is given by :

S = a + b

As we know that vectors have both magnitude and direction. Let us consider that East points in +x axis and west points in -x axis. Let the sum is given by S. So,

S = 15 m + (-9 m)

S = 6 meters

So, the vector sum of 15 m, East and 9 m, West is 6 m not 24 m. Hence, the given statement is false.
