Section – B – (Comprehension Type)
This section contains 2 paragraphs. Based upon the each paragraph 3 multiple choice questions have to be answered. Each of these questions has four choices (A), (B), (C) and (D) out of which ONLY ONE is correct.
Paragraph-1
Two bodies A and B are rubbed together, on rubbing some charges are transfered from one body to another body and hence bodies get charged. The process is called the charging by friction.
15. About the charges on A and B,
(A) both get opposite nature of charge
(B) both get positively charged
(C) both get negatively charged
(D) nothing can be concluded
16. About quantity of charge on A and B,

(B) The quantity of charge on the body is inversely proportional to its size.
(C) The quantity of charge on both A and B is same.
(D) The positive charge will be more than the negative charge.
17. The charging is due to
(A) flow of electron (B) flow of protons (C) flow of nucleus (D) flow of ions
Paragraph-2 :
Two persons Roshan and Kunal are holding a rope and they both are pulling the rope. Mass of
Roshan is two times that of Kunal. Roshan is very strong where as Kunal is weak. As per Newton’s
third law of motion, for every action there is equal and opposite reaction. The action and reaction
acts on two different bodies in opposite directions.
18. Force on the rope by the Roshan is F1 and that due to Kunal is F2. Then
(A) F1 = F2 (B) F1 > F2
(C) F1 < F2 (D) The relation depends on their mood
19. About force on the rope due to Roshan and by the rope on the Roshan.
(A) Force on the rope by the Roshan will be more than that due to rope on Roshan.
(B) Force on the rope by the Roshan will be less than that due to rope on Roshan.
(C) Force on the rope by the Roshan will be equal to that due to rope on Roshan.
(D) Force on the rope by the Roshan will depend on the friction between the foot of Roshan and
ground.
20. Let F1 be the force on A due to B and F2 that on B due to A. Then
(A) F1 = F2 and both the forces will be in same direction
(B) F1 ? F2 and both the froces will be in same direction
(C) F1 = F2 and both the forces will be in opposite directions.
(D) F1 ? F2 and both the forces will be in opposite directions
