Question

The magnitude of the electric

Distance from Q (m):

0.0030

0.0040

0.0050

0.0060

0.0070

0.0080

0.0090

0.0100

0.0110

0.0120

field E at various distances from a source point charge Q is:

Field (N/C)

702 x 10-12

373 x 10-12

250 x 10-12

190 x 10-12

130 x 10-12

87.6 x 10-12

82.7 x 10-12

55.3 x 10-12

45.7 x 10-12

38.5 x 10-12

Plot the data (using EXCEL), fit it with a power function, and verify that the data follows an inverse square law. Determine the magnitude of the source charge in coulombs from the fit.

Answer 1

As the charge calculated is less than the charge of an electron which is not possible that means there is some mistake in question. It may be due to different unit of distance taken or power of 10 may be mistaken. If you found correct information just replace with the one i used and you will get correct answer.. thanks.
