SUMMARY
The magnitude of the force on a calcium ion in a cell membrane with an electric field strength of 1.0x10^7 N/C can be calculated using the formula F = Eq. The charge of a calcium ion is +e, where e is approximately 1.6x10^-19 C. Therefore, the correct calculation for the force is F = 1.0x10^7 N/C * 1.6x10^-19 C, resulting in a force of 1.6x10^-12 N. This confirms that the initial assumption of +e being equal to 1 was incorrect.
