Assertion: Distance is a actual length of the path but displacement is a shortest distance between initial and final position. Reason: Distance is a scalar quantity and it is always positive but displacement is a vector quantity. It may be positive, negative or zero.

If the difference between the real roots of x^(2)+px+q=0 is the same as the difference between the real roots of x^(2)+qx+p=0 and p!=q, then the absolute value of (p+q) is
