Some students do a lab experiment to find g the accelerartion due to gravity. the value they came up with experimentally was 11.25m/s2. the actual value for g is 9.81 m/s2. what is their percent error? a 3.9 % b 14.7 % c 1.44 % d -6 %

b. 14.7%

Explanation:

Experimental value of gravitational acceleration “g” = 11.25 m/s^2

Actual value of gravitational acceleration “g” = 9.81 m/s^2

Percentage error = ((Experimental value – Actual value)/Actual value) × 100

Percentage error = ((11.25 – 9.81)/9.81) × 100                                          

Percentage error = 14.7%  

Hence, the percentage error in the value of “g” will be 14.7%.
