The discussion revolves around an electrostatic equilibrium problem involving the electric field of a sphere and its comparison to a point charge. Participants are exploring the implications of their calculations and the conditions under which the situation may be deemed impossible.
Some participants have provided calculations for the electric field, while others are reflecting on discrepancies between their results and graphical representations. The discussion is ongoing, with multiple interpretations being explored regarding the nature of the electric field in this context.
There appears to be confusion regarding the relationship between calculated values and graphical data, which may be influencing participants' understanding of the problem's feasibility.
Thank you for your reply @kuruman ! The electric field of a sphere is equivalent to that of a point charge so ## E = \frac {40 \times 10^{-9}k_e}{0.15^2} ##kuruman said:
Thanks for your reply @kuruman ! Thinking... Its got to me something to do with the electric field.kuruman said:
Yes. Look at the plot and then look at your post #3.Callumnc1 said:
Oh thanks @kuruman ! The calculated value for the electric field at the surface of the charge is not equal to that value on the graph.kuruman said:
