JEE MAIN PATTERN ANALYSIS
Master These 10 PYQs
This isn't just a list. It's a strategic breakdown of the ten most important concepts disguised as questions, revealing the patterns NTA loves to test.
The Philosophy Behind the Selection
These "must-know" questions were chosen because they represent recurring, high-impact concepts based on a deep analysis of the last 7 years of papers.
The Photoelectric Effect
When light of frequency 2ν₀ (where ν₀ is the threshold frequency) is incident on a metal plate, the maximum velocity of photoelectrons is v₁. When the frequency is increased to 5ν₀, the maximum velocity is v₂. The ratio of v₁ to v₂ is:
1:2
2:1
1:4
4:1
Magnetic Field of a Current Loop
A wire carrying current *I* is bent into a circular arc of radius *R* subtending an angle θ at the center. The magnetic field at the center is:
μ₀Iθ / 4πR
μ₀Iθ / 2πR
μ₀Iθ / 4R
μ₀Iθ / 2R
Moment of Inertia of Composite Body
From a uniform solid disc of radius R, mass M, a smaller disc of radius R/2 is removed such that its circumference touches the center. Find the moment of inertia of the remaining part about an axis perpendicular to the plane and passing through the center of the original disc.
