Question

7. Experimental value of acceleration due to gravity is found to be
9.842 m/s². The accepted value of acceleration due to gravity is
9.81 m/s2. What is the percent error in calculation?
a 0.326 %
b 0.316 %
C 0.981 %
d 0.613 %

Answer 1

Answer : The correct option is, (a) 0.326 %

Explanation :

To calculate the percentage error, we use the equation:

$\%\text{ error}=\frac{|\text{ Experimental value - Accepted value}|}{\text{ Accepted value}}\times 100$

We are given:

Experimental value = 9.842 m/s²

Accepted value = 9.81 m/s²

Now put all the given values in above equation, we get:

$\%\text{ error}=\frac{|9.842 m/s^2- 9.81m/s^2|}{9.81m/s^2}\times 100$

$\%\text{ error}=0.326\%$

Therefore, the percent error in calculation is 0.326 %
