Step-wise Solutions to Important NEET 2018 Physics Questions
Question 1: Centripetal Force in Circular Motion
Problem: A particle in uniform circular motion doubles its speed. How does centripetal force change?
Solution:
F=mv2r ⟹ F=m(2v)2r=4mv2rF = \frac{mv^2}{r} \implies F = \frac{m(2v)^2}{r} = 4\frac{mv^2}{r}
Answer: 4× original force
Question 2: Ohm’s Law
Problem: Potential difference 20 V across 10 Ω resistor. Find current.
Solution:
V=IR ⟹ I=VR=2010=2 AV = IR \implies I = \frac{V}{R} = \frac{20}{10} = 2\,A
Answer: 2 A
Question 3: Work Done
Problem: 10 N force moves an object 5 m. Work done?
Solution:
W=F⋅d=10×5=50 JW = F \cdot d = 10 \times 5 = 50\,J
Answer: 50 J
Question 4: Photon Energy
Problem: Photon frequency 6×10¹⁴ Hz, h=6.63×10−34 J⋅sh = 6.63×10^{-34}\,J·s
Solution:
E=hν=6.63×10−34×6×1014≈3.98×10−19 JE = h\nu = 6.63×10^{-34} \times 6×10^{14} \approx 3.98×10^{-19}\,J
Answer: ≈ 4×10⁻¹⁹ J
Question 5: Gravitational Force
Problem: Two masses 2 kg and 3 kg at 1 m. G=6.67×10−11G = 6.67×10^{-11}
Solution:
F=Gm1m2r2=6.67×10−11×2×312=4.002×10−10 NF = \frac{G m_1 m_2}{r^2} = \frac{6.67×10^{-11} × 2 × 3}{1^2} = 4.002×10^{-10}\,N
Answer: 4.0×10⁻¹⁰ N
