Nuclear density is given by, ρ=34π(R0)3m, where m is mass of proton. Clearly it is independent of A and same for all nucleus.
Radius of the nucleus is given by, R=R0A31.
Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R
Assertion A : The nuclear density of nuclides B510,L36i,F2656e,N1020eandB83209i can be arranged as ρBiN>ρFeN>ρNeN>ρBN>ρLiN
Reason R : The radius R of nucleus is related to its mass number A as R=R0A31, where R0 is a constant.
In the light of the above statement, choose the correct answer from the options given below :

A voltage regulating circuit consisting of Zener diode, having break-down voltage of 10 V and maximum power dissipation of 0.4 W, is operated at 15 V. The approximate value of protective resistance in this circuit is $\_\_\_\_$ $\Omega$.
An atom ${ }_{3}^{8} X$ is bombarded by shower of fundamental particles and in 10 s this atom absorbed 10 electrons, 10 protons and 9 neutrons. The percentage growth in the surface area of the nucleons is recorded by:
In the hydrogen atom, the electron makes a transition from the higher orbit ($i$) to a lower orbit ($f$). The ratio of the radius of the orbits in given by $r_i : r_f = 16 : 4$. The wavelength of photon emitted due to this transition is _____ nm. (Given Rydberg constant $= 1.0973 \times 10^7$ /m)
The work function of a metal is 4.2 eV. The threshold wavelength for photoelectric emission is approximately:
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): The electromagnetic wave exerts pressure on the surface on which they are allowed to fall. Reason (R): There is no mass associated with the electromagnetic waves.
