    Coulomb's law Law
AI Thread Summary
To calculate the electrical force between two charged objects using Coulomb's Law, the formula F = k * (Q1 * Q2) / d^2 is used, where k is Coulomb's constant (approximately 9.0 x 10^9 N m²/C²), Q1 and Q2 are the charges, and d is the distance between the objects. In this case, the charges are 6.65000 x 10^-6 C for object X and 7.73000 x 10^-6 C for object Y, with a distance of 0.800 m between them. The user initially struggled with understanding how to apply the formula but eventually realized that the values for k, Q1, and Q2 were already provided in the correct units. After multiple attempts, the user successfully calculated the electrical force. This discussion highlights the importance of correctly applying Coulomb's Law and understanding the units involved.

Homework Statement



I have physics homework and i don't quite seem to understand the question:
Two objects ( X and Y ) are placed at a distance of .800m from each other. The charge on X is 6.65000x10^-6 C and Y is 7.73000x10^-6. What is the value of electrical force (in Newtons) between the two objects? Answer accurate to the fourth decimal place.

Homework Equations



i think the equation is F=kxQ1xQ2/d^2, but don't know how to solve for Q1 or Q2..and is K 9.0x10^9?
ive tried reading the info. they provide us over and over but still don't seem to get how to solve it

The Attempt at a Solution


:cry: i know I am a noob but please help lol
thank you

Q1 and Q2 are the charges on the objects, d is the distance between the objects, and k is Coulomb's constant
 
but the thing is i don't know where to start..

They give you all of those values, except for k which you can look up. Unless I'm missing something, all you have to do is plug them into the equation to get the force.
 
how do i get values of k, q1, and q2 in units of Coulomb?
oh wait they give it to us in C
 
oh ok..let me try that..ive tried plugging in over and over..but couldn't get the answer..
