CAPE Physics Unit 2 · 2008 (Rest of Region) · Paper 1 · Question Q38

An early experiment, working in other than SI units, obtained the following series of values for the magnitudes of the charges on minute oil drops: 19.64 \quad 39.28 \quad 09.82 \quad 39.28 \quad 34.37 \quad 19.64 \quad 24.55 29.64 \quad 19.64 \quad 39.28 \quad 34.37 \quad 24.55 \quad 09.82 \quad 14.73 What value do these results suggest for the magnitude of the charge of the electron measured in the units he used?

1. (A)4.91
2. (B)9.82
3. (C)19.64
4. (D)39.28
