Class XI Physics Sample Paper 2024 with Answer (Grade 11)

Class 11 is the foundation for your future—whether you are aiming for board exams, JEE, or NEET. But let’s be real: the jump in difficulty from Class 10 to 11 Physics is significant. Complex derivations, vectors, and rotational mechanics can be overwhelming.

That’s why we have created this Class XI Physics Sample Paper 2024. Designed strictly according to the latest rationalized syllabus, this paper bridges the gap between simply reading the chapters and actually writing the exam.

One day in the morning to take bath, I filled up 1/3 bucket of hot water from geyser.
Remaining 2/3 was to be filled by cold water (at room temperature) to bring the mixture
to a comfortable temperature. Suddenly I had to attend to some work which would take,
say 5-10 minutes before I can take bath. Now I had two options: (i) fill the remaining
bucket completely by cold water and then attend to the work; (ii) first attend to the work
and fill the remaining bucket just before taking bath. Which option do you think would
have kept water warmer? Explain.
