| Re: KVPY Mock Test
Hey !! As per your demand here I am providing you Sample paper of KVPY Stream SA Some of the Questions of Physics of this Paper is : A block of mass m sliding down an incline at constant speed is initially at a height h above the ground. The coefficient of kinetic friction between the incline is µ. If the mass continues to slide down the incline at a constant speed, the energy dissipated by friction by the time the mass reaches the bottom of the incline is – (A) mgh/µ (B) mgh (C) p mgh/sin 0 (D) mgh sin 0 The energy required to remove both electrons from the helium atom in its ground state is 79.0 eV. The energy required to ionize helium (i.e. to remove one electron) is – (A) 24/6 eV (B) 39.5 eV (C) 51.8 eV (D) 54.4 eV 23. A proton moves in the +ve z- direction after being accelerated from rest through a potential difference V. The proton then passes through a region with uniform electric field E in the +x direction and a uniform magnetic field B in the + y-direction, but the protonís trajectory is not affected. If the experiment is repeated using a potential difference of 2V, the proton will be – (A) deflected in the +ve x- direction (B) deflected in the ñve x-direction (C) deflected in the +ve y- direction (D) deflected in the ñve y- direction A hydrogen gas filled ballon left free in a fast but uniformly moving bus (with closed doors and windows, so not air currents) rises and touches against the ceiling of the bus. If the bus slow down quickly with uniform retardation of magnitude (A) The ballon displace in the direction of motion of the bus. (B) The ballon displaces opposite to the direction of motion of the bus. (C) The ballon remains where it was before. (D) The ballon displaces along to the vertical determined by the ratio Blamer lines of deuterium atoms, compared to those of hydrogen atom, are observed to be of – (A) higher frequency (B) higher wavelength (C) same wavelength but reduced intensity (D) same wavelength and intensity   |
