Two forces have the same magnitude ?F?. What is the angle between the two vectors if their sum has a magnitude of (a) 2?? (b) (c) zero? Sketch the three vectors in each case.

Solution 1E Step 1 of 3: (a) 2F Two force having equal magnitude , F | 1 |= F| 2| = F . Here in the given case, the total net force is, F =2F | t| To have net force as 2F, F =tF + F 1 2 Both forces should be in same direction and parallel to each other, as shown below Therefore, angle between the two forces must be zero degree or 0 . 0
