a
3.9 %
b
14.7 %
c
1.44 %
d
-6 %

[tex] \frac{11.25 - 9.81}{9.81} \times 100 = 14.7\%[/tex]

Answer:

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%.
