1420 ms-1
500 ms-1
460 ms-1
330 ms-1
Question 2
This question contains Statement -1 and Statement-2. Of the four choices given after the statements,choose the one that best describes the two statements. Statement – I:Energy is released when heavy nuclei undergo fission or light nuclei undergo fusion.and Statement – II: For heavy nuclei, binding energy per nucleon increases with increasing Z while for light nuclei itdecrease with increasing Z
Statement – 1is false, Statement – 2 is true
Statement – 1 is true, Statement – 2 is False.
Statement – 1is true, Statement – 2 is true; Statement -2 is correct explanation for Statement-1.
Statement – 1is true, Statement – 2 is true; Statement -2 is not  a correct explanation for Statement-1.
Question 3
This question contains Statement -1 and Statement-2. Of the four choices given after the statements,choose the one that best describes the two statements. Statement – I:For a mass M kept at the centre of a cube of side ‘a’, the flux of gravitational field passing through itssides is 4π GM.and Statement – II: If the direction of a field due to a point source is radial and its dependence on the distance ‘r’ for thesource is given as 1/r2, its flux through a closed surface depends only on the strength of the sourceenclosed by the surface and not on the size or shape of the surface
Statement – 1is false, Statement – 2 is true.
Statement – 1is true, Statement – 2 is true; Statement -2 is not a correct explanation for Statement-1
Statement – 1 is true, Statement – 2 is False.
Statement – 1is true, Statement – 2 is true; Statement -2 is correct explanation for Statement-1.
Question 4
A working transistor with its three legs marked P, Q and R is tested using a multimeter. No conduction is found between P and Q. By connecting the common (negative) terminal of the multimeter to R and the other (positive) terminal to P or Q, some resistance is seen on the multimeter. Which of the following is true for the transistor?
It is an npn transistor with R as base
It is a pnp transistor with R as emitter
It is a pnp transistor with R as collector
It is an npn transistor with R as collector
Question 5
A block of mass 0.50 kg is moving with a speed of 2.00 m/s on a smooth surface. It strikes another mass of 1.00 kg and then they move together as a single body. The energy loss during the collision is
0.67 J
0.34 J
0.16 J
1.00 J
Question 6
Suppose an electron is attracted towards the origin by a force k/r where ‘k’ is a constant and ‘r’ is thedistance of the electron from the origin. By applying Bohr model to this system, the radius of the nth orbital of the electron is found to be ‘rn and the kinetic energy of the electron to be Tn . Then which of the following is true?
Tn ∝ 1/n, rn ∝ n
Tn ∝ 1/n, rn ∝ n2
Tn ∝ 1/n2,  rn ∝ n2
Tn independent of n , rn ∝ n
Question 7
A wave travelling along the x-axis is described by the equation y(x, t) = 0.005 cos (αx − βt). If the wavelength and the time period of the wave are 0.08 m and 2.0 s, respectively, then α and β inappropriate units are
α = 12.50  π,  β = π/2.0
α = 25.00 π, β = π
α = 0.04/ π, β = 1.0/ π
α = 0.08/ π, 2.0/ π
