Question

7.
A is a vector of magnitude 2.7 units due east. What
is the magnitude and direction of vector 4 A?
(1) 4 units due east (2) 4 units due west
(3) 2.7 units due east (4) 10.8 units due east​

Answer 1

Answer:

1st answer magnitude will be quadrupled but direction remains same direction=4×2.7

=10.8 units

2nd answerA vector is an object that has both a magnitude and a direction. Geometrically, we can picture a vector as a directed line segment, whose length is the magnitude of the vector and with an arrow indicating the direction. The direction of the vector is from its tail to its head.

3rd answer Direction will be same

ie. Mag =2.7×4

=10.8

4th answer 14AT=4× 2.7

=8×2.7= 10.8

Direction same
