The vector -b has a magnitude of 25 m and makes an angle of 30 degrees with the +x axis. which is true about the vector b? a. it has the same direction as, but has a magnitude of 25 m b. it makes an angle of -30 degrees with the +x axis c. it has a magnitude of 25 m d. it has the opposite direction as b and a magnitude of -25 m.

The given figure shows the arrangement of vectors

-B is acting with a magnitude of 25 with

So vector B is along the opposite direction of vector -B

Statement A is wrong since the direction is opposite

Statement B is also wrong since it makes

Statement C is correct since it has 25 m magnitude

Statement D is wrong because vector's magnitude cannot be negative.

So option C is the correct answer.
