Assertion: If hat(i) and hat(j) are unit Vectors along x-axis and y-axis respectively, the magnitude of Vector hat(i)+hat(j) will be sqrt(2) Reason: Unit vectors are used to indicate a direction only.

Assertion: If hat(i) and hat(j) are unit Vectors along x-axis and y-ax

1.	Assertion: If hat(i) and hat(j) are unit Vectors along x-axis and y-axis respectively, the magnitude of Vector hat(i)+hat(j) will be sqrt(2) Reason: Unit vectors are used to indicate a direction only.
Answer» SOLUTION :Since `hati and hatj` are UNIT vectors, their magnitude are `\|hati\| = 1 and \|hatj\| = 1` . Magnitude of resultant vector is equal to `sqrt(\|hati\|^(2) + \|hatj\|^(2)) = sqrt((1)^(2) + (1)^(2)) = sqrt(2)`
