o lab and submit them online via Blackboard. 1. Given the vectors a and b shown on the right, sketch to the right a the difference c = b - a. Label the vectors. 2. Given the vectors a and b shown on the right, sketch the a combination c = 2a + b. Label the vectors.6. Three forces are applied to an object as shown in the F, = 15N figure to the right. Are these forces equal? If not, why not? F, =15N F = 15N 150 What is the net force on the 30 object? Comfor To make the net force on the object be zero, what force (magnitude and direction) should be added to the three existing forces
