In Rutherford's nuclear model of the atom, the nucleus (radius about 10^(-15)m ) is analogous to the sun about which the electron moves in orbit (radius about 10^(-10)m ) like the earth orbits around the sun. If the dimensions of the solar system had the same proportions as those of the atom, would the earth be closer to or further away form the sun than actually it is ? The radius of earth's orbit is about is 1.5xx10^(11)m . The radius of the sun is taken as 7xx10^8m .

In a certain binary star system, each star has the same mass as our sun. They revolve about their centre of mass. The distance between them is the same as the distance between earth and the sun. What is their period of revolution in years ?

Our sun with mass 2 xx 10^(30)kg revolves on the edge of our milky way galaxy which can be assumed to be spherical having 10^(20)m Also assumee that many stars identical to our sun are unifromly distributed in the spherical milky way galaxy If the time period of the sun is 10^(15) second and number of stars in the galaxy are nearly 3 xx 10^((a)) find value of 'a' (take pi^(2) = 10, G (20)/(3) xx 10^(-11) inMKS) .

A small ball is projected at an angle alpha with an initial velocity u between two vertical walls such that in the absence of the wall its range would have been 5d . Given that all the collisions are perfectly elastic and distance between the walls be d/2 , find. (a) maximum height atained by the ball. (b) total number of collisions with the walls before the ball comes back to the ground, and (c) point at which the ball finally falls. The walls are supposed to be very tall.

Three positive point charges q_1,q_2,and q_3 form an isolated system. Suppose the charges have generated a property due to which like charges also attract. The charges are moving along a circle with same speed maintaining angles as shown in the figure. The charge q_1 experiences a force f_1 due to other two charges. Similarly, q_2 experiences a force f_2 and q_3 , a force f_3 . The ratio of f_1 : f_2 : f_3 is
