Question

please Ans. this que..and also explain it..​

Answer 1

For two vectors the maximum possible attainable value of magnitude is when they are along the same direction.

and the minimum when they are in opposite directions.

since the question is given as

c=a-b(in vector form)

The max value and min value(a-b and a+b) is possible.( 1,3 are correct.)

now if b were to travel in opposite direction as that of a.

then in vector for the equation becomes:

(c=a - (-b) =a+b). (for magnitudes)

and the min value is given in the question as c=a-b (for magnitudes)

so... (a-b) <c<(a+b)

and the question states that which of these cannont be achieved by.....

=>c can be greater than a and c can be greater than b also.(2 is correct)

(4)->wrong.

this is because in the question...

magnitude representation is c=a-b.

This cannot be achieved for all angles b/w a and b As When both the vectors are in opposite directions->value of c becomes as c=a-(-b) =a+b.

Hope it helps...
