Part I Mental Ability) costs of 50 Questions (Q. No. 1 to 50), Part-II (Language Comprehensive Test) consists of 50 Questioas (Q. Nos. Sl to 100) and Part-m (Apttude Test) consists of 100 questions (Q. Nos. 101 to 200) All questions cany one mark each. Since all questions are compulsory do not ty to read through the whole quection paper before beginning to nswer it 3. 4. 5. Begin with the fist question and keep tying one question after another till you finish all three parts 6 If you do not know the answer to any question, do not spend much tree on and pass on to next one If time permits, you can come back to the questions which you have left in the first instance and try them eun Since the time allotted to the question paper is very limited, you should make the best use of it by not pending too much time on any question 7. . A black page is provided for rough work at the end of each part, 9. REMEMBER YOU HAVE TO SHADE ANSWERS ON A SEPARATE OMR SHEET PROVIDED 10. Answer to each question is to be indicated by SHADING the cirele having the number of the correct II. 12. 13. The candidate need not return this Question Paper booklet and ean take it after completion of the alternative in OMR Sheet firom among the ones given for the corresponding question in the booklet. Now turn to the next page and start an:wering the questions. After the examination, you should hand over the OMR Sheet to the Inviglator of the room examination. No candidate should leae the examination hall before the end of the examination Mental Ability and Scholastic Aptitude Test Name of the Candidate : Registration No. School Name

9112-11-=-2gH 8u- -4u2 .:. -ve sign indicates the downward direction of displacement
When the speed of a particle is doubled, the ratio of its kinetic energy to its momentum: (A) remains the same (C) becomes half 3. (B) gets doubled (D) Becomes four times Sol. (B) Given Let initial speed u Initial momentum. (P) = mu Initial K.E.-1/2 mu- miu KE P Ratio of K. E. and P = miu lt Initial Ratio = 2 Final speed 2u Final momentum (P) = m(2n) = 277111 Final KE -m(211)-=-m x 41,-=2"m KE 2mu2 P 2miu Final ratio of-=- 11 Final Ratio = u Final Ratio of KE and P is double that of initial ratio
