    Magnitude of the electrostatic force

    Yes we are learning the law right now. But i am not sure what to do with the "m" given, do i add them all...? I am so lost.

    Magnitude of the electrostatic force

    Hello, Any help woould be wonderful! Identical point charges Q are placed at each of the four corners of a rectangle measuring 2.35 m by 3.05 m. If Q = 26.9 μC, what is the magnitude of the electrostatic force on anyone of the charges? i don't even know where to start... HELP!

    What Force Acts on a Marble at Point Q in a Loop-the-Loop?

    It said 3.34 was right tho.. :(. I still don't understand how to get part B

    What Force Acts on a Marble at Point Q in a Loop-the-Loop?

    Collinsmark was my 3.24m. Is what you are referring as not right? Would v=sqroot g(R-r). Be the right track?

    What Force Acts on a Marble at Point Q in a Loop-the-Loop?

    Help please -- marble rolling around loop-the-loop A solid marble of mass m = 15 kg and radius r = 8 cm will roll without slipping along the loop-the-loop track shown in the figure if it is released from rest somewhere on the straight section of track. The radius of the loop-the-loop is R =...

    Max Angle for Block to Roll Without Slipping: 29.24°

    nevermind! got it! it was (3 tanθ)+(tan-1 (3tanθ)!

    Max Angle for Block to Roll Without Slipping: 29.24°

    Thank you for the help! ... i am using eq (3 tanθ)(tan-1 (3tanθ) and its not working :( what am i doing wrong?

    i am so confused.. how can you find the "arc" that you are plugging into "arc tan(0.56) = 29.24 deg" i tried this and i am LOST! helppp!

    What is the Tension in a Connecting Cord for Two Masses on an Incline?

    i still get it wrong.. i don't understand how to get "a" when tension is in the eq... F-(tension+m*g*sin(35)) = m2*a ...(1) :( helppp

    What is the Tension in a Connecting Cord for Two Masses on an Incline?

    i don't understand what mgsin is... are you talking about m1 or m2? help i am trying to figure this problem out and i still don't get it...
