    Time Period of SHM: Opposite Charges in Springs

    I haven't yet learned Taylor expansion. So is there any other method ? I actually found this question in a magazine. The answer page was torn. So i don't know the answer too. I have tried solving it 8-10 times but with no success ! (cant reach the final expansion) I found this sum interesting...

    Time Period of SHM: Opposite Charges in Springs

    But what about the electrstatic force. It constantly changes as the distance between the charges change. how to incorporate that. I know by intergrating the force, but then what to do?

    Time Period of SHM: Opposite Charges in Springs

    1. Homework Statement Two Springs are present (one just infront of the other). The Spring towards the left has +Q charge and towards the right -Q charge (at their ends).The distance between the two charges is d. The Springs are of length l. Find the Time Period of the Simple Harmonic Motion...

    Calculating Acceleration & Velocity of an Electron in Electric Field

    Homework Statement Velocity components of an electron moving between two charged paralle plates are Vx=(1.5*10^5 m/s) and Vy=(3*10^6 m/s). Electric field between the plates is E=(120 N/C) j Find 1) Accleration of electron 2) Velocity of electron after its x-coordinate has changed by 2 cm...

    A charge +Q is fixed. Another charge +2q and mass M is projected

    Ok.. so is this the way ? M (√3/2)v R1 (1/2) = M (v/2) R2 therefore , R2 = (√3/2)R1 (so what is the use of energy conservation?) and I was thinking about the path of +2q charge. It would be repelled by the +Q charge, so it shouldn't move towards the +Q charge. So how will the path of +2q...

    A charge +Q is fixed. Another charge +2q and mass M is projected

    Homework Statement A charge +Q is fixed. Another charge +2q and mass M is projected from a distance R from the fixed charge at and angle 30 with the horizontal towards the fixed charge (like a projectile) at a speed of v Find the minimum separation between the two charges if the velocity...
