Q2. A body of mass 0.40 kg moving initially with a constant speed of 10 m /s to the north is subject to a constant force of 8.0 N directed towards the south for 30 s. Take the instant the force is applied to be t = 0, the position of the body at that time to be x = 0, and predict its position at t = –5 s.
Answer : Option B
Explaination / Solution:
Let ,
At t= -5 s, there is no force acting on the particle,
so,

Q4. When pentanal reacts with ethylamine under conditions of acid catalysis, the major organic product is __________.
Answer : Option C
Explaination / Solution:
Imines are typically prepared by the condensation of primary amines and aldehydes and less commonly ketones:
- RNH2 + R'C(O)R → RN=C(R')(R) + H2O

Answer : Option D
Explaination / Solution:
Calcium is a silvery-white metal; it is relatively soft, but much harder than sodium metal. Calcium is a member of the alkaline-earth metals (Group II on the periodic table); these metals react vigorously with water, although not as violently as the Group I metals such as sodium or potassium:

Q10. For a charged conductor of arbitrary shape, inside the conductor
Answer : Option C
Explaination / Solution:
The electric field on the surface of a hollow conductor is maximum and it drops to zero abruptly inside the conductor. Since, the potential difference between any two points inside the hollow conductor is zero. This means that the potential at all points inside the hollow charged conductor is same and it is equal to the value of the potential at its surface.
