Two vectors, of magnitudes 20 and 50, are added. which one of the following is a possible answer for the magnitude of the resultant?
a. 10
b. 20
c. 40
d. 80.

(c) 40

Step-by-step explanation:

Given

Magnitude of first vector is 20 units

Magnitude of second vector is 50 units

From the given data we can say that maximum magnitude of resultant vector is 70 units if the angle between is

and the minimum value of resultant is 50-20=30 if they are apart

So the resultant must lie between 30 to 70

Thus c is the only option which satisfy the above deductions.

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
