SUMMARY
The electric field strength required to suspend a proton at rest against gravity is calculated using the formula E = F / q, where F is the force due to gravity and q is the charge of the proton. Given the mass of the proton (1.67 x 10^-27 kg) and the gravitational acceleration (9.81 m/s²), the correct electric field strength is determined to be approximately 1.02 x 10^-7 N/C. This calculation confirms that the initial answer provided is accurate.
