Question

a vector of magnitude 20 is added to a vector of magnitude 25.the magnitude of this summight be.

Answer 1

it could be 45 if the vectors are parallel
it could be 5 if the vectors are anti-parallel or it could be somewhere between 20 and 25 if the vectors are inclined at an angle theta with each other.....
hope this helps u......
the answer cannot be less than 5 and greater than 45....
mathematically:
5 is less than resultant,resultant is less than 45......
have a wonderful day ahead.....

Answer 2

In mathematics, magnitude is the size of a mathematical object, a property which determines whether the object is larger or smaller than other objects of the same kind. More formally, an object's
