1. Reply the answer to the 40th question is (c) and for the 41st question it is (b)

2. Reply the answer to the 32nd question is (c) —— which is 0.98N ,
friction force = normal reaction ( coefficient of friction)
f= (1kg * 9.8)*0.1 = 0.98N

• Reply wrong thts max static friction , but force is on .8 so it cant reach .98. hence answer .8

• Reply a/c to me answer should be .8N because acting force(.8N) is less than .98N.

3. Reply the answer to the 18th question is (a) ,which is ——increase in coefficient of friction

4. Reply the answer to the 9th question (coefficient of restitution of plastic impact is 0) —– (A)

• Reply A perfectly elastic collision has a coefficient of restitution of 1. Example: two diamonds bouncing off each other. A perfectly plastic, or inelastic, collision has c = 0.

• Reply correct

• Reply yeah but coefficient of restitution of plastic collision was asked….even I didn't read the q. properly and marked 1

5. Reply is general paper of mechanical n chemical engineering was same???

6. Reply is GENEral paper of mechanical n chemical was same?

• Reply nope.. chemical paper was not not so easy as mechanical .. i can surely say you mechanical paper can be solve by a 12th class student

• Reply Why not GATE keep eligibility criteria for Mechanical as 12th and for chemical Graduation ?
