24.A force of magnitude 1 N, acts on a particle of mass 2 kg. Position vector of particle is 6(m) from origin. The torque generated by force is 33Nm about origin. The acute angle between force and position vector is radians. The value of n is n 25.Davisson-Germer experiment demonstrated that electrons exhibit wave behavior. If an electron beam is incident on Young's double slit set up, the separation between two successive localized accumulation of electrons on the screen is 'x' m. Find x. Use the information given. (Separation between slits = 10 m, Separation between slits plane and screen = 1m, kinetic energy of electron in beam = 5eV, mass of electron = 9 10- kg. Charge on electron = 1.6 10-1C, planks constant = 6.6 10-34Js) 26.A network of resistors is connected to a 16 V battery with internal resistance of 1 as shown in the figure. Then voltage drop VAB is equal to (in volts) 402 1292 www. B www. WWW www. www 402 www 16V
