so is the mass not important??

Homework Statement A point charge Q resides at the origin. A particle of mass 0.001kg carries a charge of 6 microC. The particle is released from rest at x = 3m. Its kinetic energy as it passes x = 0.5m is 0.4J. The coulomb constant is 8.99x10^9Nm^2/C^2. Find the charge Q. Answer in microC...

Ta cos 22 + Tb cos 53 + 11*9.8 = 0 Ta sin 22 + Tb sin 53 = 0 solve simultaneously and I got the answer! Ta=166.9 Tb=78.12 thank u so much!

Ok, let's see: for A: x=mg cos theta + mg y=mg cos theta + mg answer = square root x^2+y^2 ? Sorry, I'm a bit lost.

[URGENT]Static Equilibrium problem A 11kg ball is supported from the ceiling by rope A. Rope B pulls downward and to the side on the ball. If the angle of A to the vertical is 22 degree and if B makes an angle of degree to the vertical find the tension in rope A. Homework Equations sum...
