A physical quantity X is connected from X = ab2/C. Calculate percentage error in X, when percentage error in a, b, c are 4,2 and 3 respectively.

Answer: 11%

Explanation:

Given that

X = ab^2/C. Calculate percentage error in X, when percentage error in a, b, c are 4,2 and 3 respectively.

Percentage error of b = 2%

Percentage error of b^2 = 2 * 2 = 4

When you are calculating for percentage error that involves multiplication and division, you will always add up the percentage error values.

Percentage error of X will be;

Percentage error of a + percentage error of b^2 + percentage error of c

Substitute for all these values

4 + 4 + 3 = 11%

Therefore, percentage error of X is 11%
