| Direction: For the following questions choose the correct answers from the codes [a], [b], [c] and [d] defined as follows. |
| Statement I Systematic errors have same size and sign for all measurements. |
| Statement II While computing systematic error in some physical quantity, say X, which AB depends on other physical quantities, say A, B and C, by the expression \[X=\frac{AB}{{{C}^{2}}}\], we won't consider the worst case. |
A) Statement I is true. Statement II is also true and Statement II is the correct explanation of Statement I.
B) Statement I is true. Statement n is also true and Statement II is not the correct explanation of Statement I.
C) Statement I is true. Statement II is false.
D) Statement I is false. Statement II is true.
Correct Answer: A
Solution :
The cause of systematic errors are known to us that is why they always have same size and sign in a measurement and because of this reason only we don't consider the worst case. While in random errors, the case is reverse.
