Question

5. What do you understand by the combination of errors?
If P = x^alpha y^beta z^gama then, obtain expression for percentage
error in P.​

Answer 1

Answer:

• To measure any physical quantity, we compare it with a standard (unit) of that quantity. No measurement is perfect as the errors involved in the process cannot be removed completely. Hence, in spite of our best effort, the measured value of a quantity is always somewhat different from its actual value, or true value.
