Sample Questions for Section on Numerical Value

Q.1: A particle moves in the x-y plane under the influence of a force such that the linear momentum Is P(t) = A [ î cos kt - ĵ sin kt ]

Where A and k are constants. The angle in degrees between force and momentum is .

Answer: 90

Q.2: A power line lies along the east - west direction and carries a current of 10 A. The force per meter due to earth's magnetic field of 10^-4 T is 10^-X N/m. The value of x is .

Q.3: The sun's disc subtends an angle of 10^-2 rad at the earth. The radius of curvature ( in meters) of the mirror which will produce on a screen an image of the sun 2 cm in diameter is .

Q.4: The binding energy of deutron (₁H²) is 1.15 MeV per nucleon and an alpha particle ( ₂He⁴ ) has a binding energy of 7.1 MeV per nucleon. Then in the reaction ₁H² + ₁H² → ₂He⁴ + Q

The energy Q released in MeV is

Answer : 23.8

sir I qualified jee mains but i got less rank In emacet then I can join top 10 engineering colleges

Bhaskar Nakkina Student Expert 12th Nov, 2019

Hii,

EAMCET and JEE Mains are both different exams. EAMCET is a state level Entrance Test to get admission in local Engineering Colleges and JEE is a National level Entrance Test to get admission in Engineering Colleges all over India. So If you are not able to make a good Score in EAMCET you won't get better College in state level. If you have good JEE percentile then apply for Colleges based on that Score.

Hi Atithya,

JEE is one of the most difficult entrance examination in not only India, but in the world. However, it can be cracked. For doing so, you need to make a rigid but realistic timetable and strictly adhere to it. You need to be able to focus on what's important and block out everything else. You have to be able to study with concentration and dedication for hours on end.

can i will get nit patna CSE after getting 150 marks in jee mains with home state quota..

Devraj choudhary Student Expert 12th Nov, 2019

Hii

It is impossible to predict for now with only marks. Because after the normalization of score is done the rank varies to a large extent. Last year a student with 220 marks was having 22000 rank at same time with 181 was in top 10000.

So, basically is that onec you get the rank than only it can be predicted. Before the NTA the thing was clear and normalization was not done.

At last I can guess that even with 150 marks for home state won't be enough to fetch a CSE seat.

Hope it helps
