Question

find the vector which has magnitude of 10 unit ans it's direction is parallel to the vector 12i-5j​

Answer 1

Answer:

120i-50j/13

Step-by-step explanation:

First we need to find a unit vector of the given vector

∴Magnitude = √[12² + (-5)²] = 13

Now Unit vector = Given vector/Magnitude

∴Unit vector = (12i-5j)/13

∵Unit vector has magnitude 1 and is parallel to given vector

∴Vector parallel to 12i-5j having magnitude 10 will be = (12i-5j)/13 × 10

= (120i-50j)/13
