How are these dpps useful to u?

1)These dpps can be used to prepare for various Engineering as well as Medical exams such as IT JEE Mains & Advance, MHT CET, VITEEE, KIITEE, WBJEE ,NEET, AIIMS, JIPMER, PGIMER), CBSE Board, ICSE Board, Class 12th, 11th.

2) We are providing u very important dpps which can be proven useful to Many students to crack competitive exams as well as board examinations

MCQS

1. A block of mass M is attached to the lower end of a vertical rope

of mass m. An upward force P acts on the upper end of the rope.

The system is free to move. The force exerted by the rope on the

block is PM/M + m

(a) in all cases (b) only if the rope is uniform

(c) in gravity-free space only (d) only if P > (M + m)g

Solutions- At the end

2. A man slides down a light rope whose breaking strength is n

times his weight (n<1). What should be his maximum

acceleration so that the rope just breaks?

(a) ng (b) g(1 - g)

(c) g/1+n (d) g/2 - n

3. A particle of a small mass m is joined to a very heavy body by a

light string passing over a light pulley. Both bodies are free to

move. The total downward force on the pulley is

(a) mg (b) 2 mg

(c) 4 mg (d) >> mg

Solutions- At the end

4. A uniform chain of mass m hangs from a light pulley, with

unequal lengths of the chain hanging from the two sides of the

pulley. The force exerted by the moving chain on the pulley is

(a) mg

(b) > mg

(c) < mg

(d) either (b) or (c) depending on the acceleration of the

chain

5. A strip of wood of length l is placed on a smooth horizontal

surface. An insect starts from one end of the strip, walks with

constant velocity and reaches the other end in time t1. It then flies

off vertically. The strip moves a further distance l in time t2.

(a) t2 = t1

(b) t2 < t1

(c) t2 > t1

(d) Either (b) or (c) depending on the masses of the insect and

the strip

Solutions- At the end

6. In a tug-of-war contest, two men pull on a horizontal rope from

opposite sides. The winner will be the man who

(a) exerts greater force on the rope

(b) exerts greater force on the ground

(c) exerts a force on the rope which is greater than the tension

in the rope

(d) makes a smaller angle with the vertical

Solutions- At the end

7. A bicycle moves on a horizontal road with some acceleration.

The forces of friction between the road and the front and rear

wheels are F1 and F2 respectively.

(a) Both F1 and F2 act in the forward direction.

(b) Both F1 and F2 act in the reverse direction.

(c) F1 acts in the forward direction, F2 acts in the reverse

direction.
