Question

A is a vector of magnitude 2.7units due east.what is the magnitude and direction of vector 4 A

Answer 1

Magnitude will be quadrupled but direction remains same.
Magnitude = 4 ×2.7 = 10.8 units

Answer 2

The magnitude for the given vector is 10.8 units.

Given:

Magnitude of the vector=2.7 units

Direction of the magnitude is in the east direction

To find:

We have to find the direction and magnitude of vector 4A

Solution:

Magnitude $= 4 \times 2.7$

= 10.8 units.

Hence the magnitude of the vector 4 A is 10.8 units

Direction = East

When a vector is multiplied by a number then its direction always remains the same.

Vector: it has two or more defining characteristics

Magnitude: 10.8 units.
