If the ratio of the radius of a nucleus with 61 neutrons to that of helium nucleus is 3 , then the atomic number of this nucleus is

If the ratio of the radius of a nucleus with 61 neutrons to that of helium nucleus is 3, then the atomic number of this nucleus is

If the radius of a nucleus ""^(256) X is 8 fermi , then the radius of ""^(4) He nucleus will be

The radius of a sphere is 1.41 . its volume to an appropring number of significant figure is

The radius of a gold nucleus (Z=79) is about 7.0 xx 10^9-15) m . Assume that the positive charge is distributed uniformly throughout the the nuclear volume. Find the strength of the electric field at (a) the surface of the nucleus and (b) at the middle oint of a radius. Remembering that gold is a conductor, is it justifild to assume that the positive charge is uniformly distributed over the entire volume of the nucleus and does not come to the ourer surface?

If the radius of a sphere becomes 3 times then its volume will become
