Question

the resuultant of two force 10 N and 15 N acting along +x and -x axes respectively is a 25 N along+ axis b 25 N along +- x axis c 5 N along ​

Answer 1

Here the two forces are in opposite direction, so simply we can get that the resultant is towards the larger one, and its magnitude is the difference of the two vectors.

Here the larger force is of 15 N towards - x direction.

Hence the resultant force is of 15 - 10 = 5 N acting towards - x direction.
