I feel like they are going to make a right triangle, but I was thinking the answer was e. If the vectors go in opposite directions well at least one of the longest ones has to be negative and the other two have to add up in order to be equivalent to the longest one so when the vectors combine...
For three vectors to add up to zero, what must be true of the magnitudes of the three vectors? Hint: Draw a diagram of the addition of three vectors to make a vector of zero length. Think of what geometrical relationship they must have.
a. All the magnitudes must be equal.
b. One of the...
