270401 Six particles each of mass ' \(m\) ' are placed at the corners of a regular hexagon of edge length ' \(a\) '. If a point mass ' \(m_{0}\) ' is placed at the centre of the hexagon,then the net gravitational force on the point mass is

1 \(\frac{6 G m^{2}}{a^{2}}\)
2 \(\frac{6 G m m_{0}}{a^{2}}\)
3 Zero
4 \(\frac{6 G m}{a^{4}}\)
Gravitation

270402 If suddenly the gravitational force of attraction between earth and satellite revolving around it becomes zero, then the satellite will (2002A)

1 Continue to move in its orbit with same velocity
2 Move tangential to the original orbit with the same velocity
3 Becomes stationary in its orbit
4 Move towards the earth

270399 Two equal masses separated by a distance \(d\) attract each other with a force ( \(\mathbf{F}\) ). If one unit of mass is transferred from one of them to the other, the force

1 does not change
2 decreases by\(\left(G / d^{2}\right)\)
3 becomes\(d^{2}\) times
4 increases by\(\left(2 G / d^{2}\right)\)
Gravitation

270392 Law of gravitation is not applicable if
A)Velocity of moving objects are comparable to velocity of light
B) Gravitational field between objects whose masses are greater than the mass of sun.

1 A is true,\(B\) is false
2 A is false,\(B\) is true
3 Both A \& B are true
4 Both\(A \& B\) are false
