A proton with speed v = 2.92 x 10^3 m/s orbits just outside acharged sphere of radius r = 1.32 cm. What is the charge incoulombs on the sphere?

Number ____ C

I used [Q = mv2 r / k q] and I got an answer of Q=1.30875289E-13but this is not correct.

A proton with speed v = 3.00 X 10^5 m/s orbits just outside a charged sphere of radius r = 1.05 cm. What is the charge on the sphere?

A ring of radius R has charge Q. At a point on the axis of thering, a distance y above the plane of the ring, the electricpotential (voltage) is . Use the voltage to find the y-component ofthe electric field at the point. Do NOT integrate directly to getfield! The answer should be entered in symbols R, Q, k, y, andnumbers.

If only electric forces are important Conservation of MechanicalEnergy tells us . In practice the electric force is frequently muchlarger than the gravitational force, and we can eliminatefrictional or drag forces by using a vacuum system. The the onlypotential energy is the electrostatic potential energy, .

An electron has a speed of 5.0 x 10^5 m/s at point A. The voltageat point A is 3300 V and at point B is 4550 V.

(a) What is the speed of the electron at point B? Assume forcesother than the electric force are negligible.

(b) Repeat the question for a proton instead of an electron.

I was able to figure out the answer to part 1, so I just need helpwith part 2. The full question is:

Assume the Earthâs magnetic dipole moment is aligned with theEarthâs rotational axis, and the Earthâs magnetic field iscylindrically symmetric (like an ideal bar magnetic).
What speed would a proton need to orbit in an exact circle aroundthe Earth at a height of 1440 km, where the Earthâs magnetic fieldhas an intensity of 4.65 Ã 10-8 T? The mass of a proton is 1.67262Ã 10-27 kg and the radius of Earth is 6.37 Ã 106 m.
Answer in units of m/s.

The correct answer is: 3.47e7 m/s

Here's the part I need help with:

The protonâs velocity is in

1. a polar orbit.

2. an equatorial orbit from west to east.

3. an equatorial orbit from east to west.

Thanks!
