Question

A vector of magnitude 5N due west is added to a vector of magnitude 6N due south. What is the magnitude of the resultant

Answer 1

Answer: The magnitude of the resultant is approximately 7.81

Explanation: To find the magnitude of the resultant we use Pythagoras theorem because the two vectors are perpendicular to each other.

so, R^2 = 5^2 + 6^2

R^2 = 25 + 36

R^2 = 61

R = square root of 61

R = 7.81
