Question

If a vector A is multiplied by a scalar number -83, the result is ___ a. 83A, is a scalar. b. 83A, is a vector pointing in the direction of A. c. -83A, is a vector pointing opposite to the direction of A. d. 41.50A, is a scalar

Answer 1

Hey there!

Answer:

c. -83A, is a vector pointing opposite to the direction of A

Since the scalar number multiplied to the vector A is negative, the directions of vector A and resultant vector (.i.e., -83A) will be different.

Scalar numbers that are negative integers (n < 0, where n is a scalar number multiplied to a given vector A).

The "-" sign in a given vector always denotes the opposite direction.

Thanks!
