Which of the following Statements is correct?

The rate of radioactive decay cannot be controlled but that of nuclear fission can be controlled

Nuclear forces are short range, attractive and charge dependent

Nuclei of atoms having same number of neutrons are known as isobars.

Wavelength of matter waves is given by de Broglie formula but that of photons is not given by the same formula

(AIEEE-2012)

Solution

Radioactive decay is a continuous process . Rate of radioactive decay cannot be controlled. Nuclear fission can be controlled but not of nuclear fusion
