NEET 2019:When an object is shot from the bottom of a long smooth inclined planekept at an angle 60∘

For NEET Physics preparation, focus on NCERT textbooks first, then move to reference books. Create a topic-wise study plan covering Mechanics, Thermodynamics, Electromagnetism, Optics, and Modern Physics. Solve previous years’ questions and take regular mock tests. Pay special attention to conceptual clarity and numerical problem-solving skills.

Lenses form images by refracting light rays. Convex (converging) lenses can form both real and virtual images depending on the object distance. Concave (diverging) lenses always form virtual, upright, and diminished images. The lens equation (1/f = 1/v + 1/u) relates the focal length (f), image distance (v), and object distance (u).

To solve physics numerical problems effectively, first understand the concept thoroughly. Then follow these steps: 1) Read the problem carefully and identify the given quantities and what needs to be found. 2) Draw a diagram if applicable. 3) Write down the relevant formulas. 4) Substitute the values with proper units. 5) Solve step by step. 6) Verify your answer by checking units and whether the result makes physical sense.
