Physics Numericals Solved Step by Step — AI That Shows Complete Working

Physics numericals are where most students lose marks. Not because they don't know the formula — but because they miss steps, forget units, or apply the wrong concept. Here's an AI that solves numericals the way examiners want to see them.

The Numerical Problem

A typical Class 12 Physics numerical:
"A convex lens of focal length 20 cm forms an image at 60 cm from the lens. Find the object distance."

Most students know 1/v - 1/u = 1/f. But they lose marks because:

  • Sign convention errors (which is positive, which is negative?)
  • Not writing "Given" and "To Find" sections
  • Skipping intermediate steps
  • Forgetting units in the final answer

How EaseLearn AI Solves Numericals

The doubt solver formats solutions exactly as examiners expect:

Given: f = +20 cm, v = +60 cm
To Find: u = ?
Formula: 1/v - 1/u = 1/f (Lens formula)
Solution:
1/u = 1/v - 1/f
1/u = 1/60 - 1/20
1/u = 1/60 - 3/60
1/u = -2/60
u = -30 cm

Answer: Object is at 30 cm on the same side as the incident light (negative sign indicates object is on the left of lens).

Every step. Proper sign convention. Units. Physical interpretation.
