Q13PhysicsUnit 6: Gravitation

Let

^{\prime} \boldsymbol{A}^{\prime}

be the area swept by the radial vector connecting the earth and the sun in April and May months. Then, find the area swept by the same radial vector connecting the earth and the sun in November and December months interms of

\boldsymbol{A}

Q14PhysicsUnit 6: Gravitation

As the planet revolves from point

\mathrm{P}

to point

Q,

the velocity of the planet.

Q15PhysicsUnit 6: Gravitation

Assertion Kepler's second law can be understood by conservation of angular momentum principle. Reason Kepler's second law is related with areal velocity which can further be proved to be based on conservation of angular momentum as

(\boldsymbol{d A} / \boldsymbol{d t})=\left(\boldsymbol{r}^{2} \boldsymbol{\omega}\right) / 2

Frequently asked questions

How long should a Kepler's law of planetary motion mock test take?

For a topic-level test, aim for 20–30 minutes. For a full subject mock, allow 60–90 minutes to mirror JEE timing.

What is a good score on a Kepler's law of planetary motion mock test?

Aim for 70%+ accuracy initially, then push toward 85%+ as your exam date approaches. Review explanations for every wrong answer.

Does Goodmarks score mock tests automatically?

Yes. Each MCQ is scored instantly with the correct answer and explanation shown after submission.

Can I retake the same mock test?

Pro users can generate new question sets by topic. Reattempting the same questions after a gap is excellent for retention.
