Question

In an experiment, you calculate Newton's universal gravitation constant to be 6.34×10−11 Nm2/kg2. The accepted value is 6.67×10−11 Nm2/kg2.

What is your percent error?

2.21%

3.95%

4.95%

5.21%

Answer 1

The percent error is 4.95%.

Step-by-step explanation:

To calculate the percent error, we need to use the formula:

Percent Error = |(Experimental Value - Accepted Value)| / Accepted Value x 100%

Given that the experimental value is 6.34×10-11 Nm2/kg2 and the accepted value is 6.67×10-11 Nm2/kg2,

Percent Error = |(6.34×10-11 - 6.67×10-11)| / 6.67×10-11 x 100%

Percent Error = |-0.33×10-11| / 6.67×10-11 x 100%

Percent Error = 0.33×10-11 / 6.67×10-11 x 100%

Percent Error = 0.0495 x 100%

Percent Error = 4.95%
