So if the formula is F = (kqd)/z^3, I plug in and get [(9.0E9 Nm^2/C^2)*(1.0E-9C)*(2.4E-3m)]/(0.01m)^3 = 21600 N/C Is that all I have to do to solve for the x-axis values? and how does this equation relate to part b where both charges are no longer an equal distance to the point on they y-axis?

Is it E= (qd)/kz^3 if d = the distance between the charges and z is the distance I to the point I am solving for?

Homework Statement An electric dipole is formed from 1.0 nC charges spaced 2.4 mm apart. The dipole is at the origin, oriented along they-axis. What is the electric field strength at the following points? a. (x, y) = (10 cm, 0 cm) b. (x, y) = (0 cm, 10 cm)Homework Equations Pythagorean Theorem...

WOW. I might need to take a break. Thank you for the correction help!

I tried again and got the same answer. I'm sure I have a stupid mistake somewhere Is it incorrect that 4.4MJ = 4400 J?

Homework Statement An energy storage system based on a flywheel (a rotating disk) can store a maximum of 4.4 MJ when the flywheel is rotating at 21,300 revolutions per minute. What is the moment of inertia of the flywheel? Homework Equations K= Ktranslational + Krotational Krot=...
