I want to know the chapter-wise weightage of marks in science. (syllabus of Class X).
The accepted correct value of escape velocity on earth is 11.2 km/s. As mentioned in the preface to the NCERT textbook, the matter in red border boxes in the book is non-evaluative. The chapter-wise weightage to different units of the syllabus is given in the document 'Secondary School Curriculum 2007, Volume I'. Please refer to the same.
