Question

Two vectors of magnitudes $10$ and $15$ units can never have a resultant equal to:

• A. $15$ units
• B. $3$ units
• C. $10$ units
• D. $20$ units

Answer 1

The correct option is B $3$ units

if we add vectors then 10+15=25

i.e. max vector addition is 25

if they are anti parallel

then their summation will be

15-10=5

so minimum can be 5

hence vector must be in between 5 and 25

hence 3 cannot be the summation of these two vector
