As per analysis for previous years, it has been observed that students preparing for NEET find Physics out of all the sections to be complex to handle and the majority of them are not able to comprehend the reason behind it. This problem arises especially because these aspirants appearing for the examination are more inclined to have a keen interest in Biology due to their medical background.

Furthermore, sections such as Physics are dominantly based on theories, laws, numerical in comparison to a section of Biology which is more of fact-based, life sciences, and includes substantial explanations. By using the table given below, you easily and directly access to the topics and respective links of MCQs. Moreover, to make learning smooth and efficient, all the questions come with their supportive solutions to make utilization of time even more productive. Students will be covered for all their studies as the topics are available from basics to even the most advanced.

**Q1.**The velocity of water waves υ may depend upon their wavelength λ, the density of water ρ and the acceleration due to gravity g.The method of dimensions gives the relation between these quantities as

(c) Let v

^{x}=kg

^{y}λ

^{z}ρ

^{δ}. Now by submitting the dimensions of each quantities and equating the powers of M,L and T we get δ=0 and x=2,y=1,z=1

**Q2.**In a vernier callipers, one main scale division is x cm and n division of the vernier scale coincide with (n-1) divisions of the main scale. The least count (in cm) of the callipers is

One main scale division, 1 M.S.D.=x cm One vernier scale division , 1 V.S.D.=(n-1)x/n Least count =1 M.S.D.-1 V.S.D. =(nx-nx+x)/n=x/n cm
