## In lecture c110504, while solving the question (picture below), you kept R constant which is a constant and you also kept V constant as stated in the question. Ignoring these, you came up with P1=n1T1.Then you said P1=P2. I couldn't understand that properly. We can say P is constant as volume is constant as per Boyle's law, however for that,temperature has to be constant which is not.

## Answer the question 1.4Coulomb's law for electrostatic force between two point charges and Newton's law for gravitational force between two stationary point masses, both have inverse-square dependence on the distance between the charges/masses. (a) Compare the strength of these forces by determining the ratio of their magnitudes (i) for an electron and a proton and (ii) for two protons. (b) Estimate the accelerations of electron and proton due to the electrical force of their mutual attraction when they are 1 $$\overset{\circ}{\mathrm {A}}$$ (= $$10^{-10}$$ m) apart? $$(m_p = 1.67 \times 10^{-27}\ kg, m_e = 9.11 \times 10^{-31}\ kg)$$
