please follow instruction do not do it other way follow guess method only please Solving problems in Physics, we must always use GUESS method.Guess stands for: Guess: G Here you write down what is given in the questionUnknown: U Here you list what you have to calculate, to solve for.Equations: E here you list all the formulas you need to use to solve the problemSubstitution: S This first letter S in the word, you will just substitute what is given in theformula. You do not calculate anything. The calculations will occur at the second S: Solve. Whatis very important here is to carry with you the units of measure in the formula. Not only thenumbers. This is very important, once again.Solve: S The last step, second S, you will solve what you plugged in the first S for Substitution.Very important here is to manipulate the units of measure such that the final units of measureto be proved by your work.

Answer Activity in a separate paper. Show the solution for every answer (for problem solving ones only). In presenting solution, it should be in the same sequence as the asked problem. Avoid too many erasures (to prevent this, solve first in a scratch paper and after finalizing, transfer it to the final paper for submission). Box your final answer with appropriate units. Retain 3 decimal places for intermediate value calculation. Not following instruction means a corresponding point deduction. 1. What magnitude point charge creates a 10,000 N/C electric field at a distance of 0.250 m? How large is the field at 10.0 m?
