Q1PhysicsUnit 7: Properties of Solids and Liquids

Which one is the weakest type of bonding in solids?

Q2PhysicsUnit 7: Properties of Solids and Liquids

The length of a metal wire is

l_{1}

when the tension in it is

F_{1}

and

l_{2}

when the tension is

F_{2}

. Then original length of the wire is:

Frequently asked questions

What makes a Elastic behaviour, stress-strain relationship, Hooke's Law question "important" for JEE?

Important questions test core concepts that appear frequently across JEE Main and Advanced papers — definitions, standard formulas, and classic problem types.

Which subtopics in Properties of Solids and Liquids are high-weightage?

Key areas include Elastic behaviour, stress-strain relationship, Hooke's Law. Prioritise these before moving to edge cases.

How many important questions should I revise?

Revise 30–50 important MCQs per unit in the last month before JEE. Focus on questions you got wrong at least once.

Can I practise only important questions on Goodmarks?
