The original poster is attempting to calculate the work done by an electric field in moving a proton between two points with different electric potentials, specifically from +155V to -75V. The problem involves understanding the relationship between charge, potential difference, and work done.
Some participants have provided guidance on the equation to use and have engaged in verifying calculations. There is ongoing exploration of the correct change in potential, with some participants questioning earlier calculations and suggesting corrections.
Participants are discussing the implications of potential differences and ensuring that the correct values are used in calculations. There is a focus on understanding the signs and values associated with electric potential.
Perhaps it would help if the equation was written thus:crh said:
You're on the right lines but be careful when calculating the change in potential.crh said:
Nope, something somewhat simpler than that. What is the difference between -75 and +155?crh said:
Much bettercrh said:
