Consider two concentric conductiong spheres as shown below:
The outer sphere is hollow and has a total charge of +5µC on it. Its inner radius is R1=9cm and outer radius is R2=10cm. The inner sphere has a radius of 1cm, is solid and has a charge of -3µC on it. What is the potential of the inner surface of the spherical shell? Assume that the potential at infinite distance is zero.

The source of the suns energy is a sequence of nuclear reactions that occur in its core. The first reaction is collision of two protons which fuse together to form a heavier nucleus and release energy. The two protons for this process must first approach until their surfaces are essentially in contact.
Q. Assume both protons are moving with same speed and they collide head-on. If the radius of the proton is 1.2*10^(-15)m, what is the minimum speed that will allow fusion to occur? The charge distribution within a proton is sperically symmetric so the electric field and potential outside proton is same as if it were a point charge. The mass of proton is 1.67*10^(-27) kg.
Q.Assume that proton behaves like a monoatomic gas at temp T. For two protons with KE equal to its average value so that it can undergo the process described in previous question what absolute temp is required?
