Answer 1

Explanation:

plzzz mark me as brillianties

Answer 2

Given,

The magnitude of the vector = 10 units

The direction of the required vector = 3i - 4j

To Find,

The vector with given magnitude and direction.

Solution,

First, we will find the unit vector of the direction vector.

Unit vector = (3i-4j)/√(3²+4²)

Unit vector =  (3i-4j)/5

Now,

The magnitude of the vector should be 10

So, the required vector will be

Vector = 10*(3i-4j)/5 = 2*(3i-4j)

Vector = 6i - 4j

Hence, the required vector is 6i - 4j.
