Example Prompts

Misconception correction (NCERT Physics)

▎ A student believes that if no force acts on an object, it must be at rest. How would you correct this?

IIT-JEE Electrostatics

▎ Two point charges +4 μC and −4 μC are placed 20 cm apart. Find the electric field at the midpoint between them.

NEET Neurophysiology

▎ Describe the sequence of events during an action potential, including the role of voltage-gated Na⁺ and K⁺ channels.

NCERT Class 12 Mathematics

▎ Differentiate f(x) = x² sin(x) with respect to x and simplify.

IIT-JEE Organic Chemistry

▎ Why does benzene undergo electrophilic substitution rather than addition? Explain using resonance and stability arguments.
