A new planet called "Corus" was discovered by a team of astronomers thatis 60 x 106 km away from Earth. A satellite was launched by a rocket fromEarth to reach Corus. At a specific distance from Corus, the rocket releasesthe satellite to the orbit of the planet. The satellite makes one completerevolution around Corus in 15 Earth days. If Corus has a similar mass toMars, propose a suitable mass of the satellite and estimate:i. ii. Distance between the satellite and the Corus's surfaceSatellite's gravitational acceleration towards the core of CorusGravitational force between the satellite and the CorusMinimum speed of the satellite to orbit Corusiv.

CASE BASED QUESTIONif two or more resistance or connected in such a way that the same potential difference get applied to each of them,then they are said to be connected in the parallel. The current flowing through the two resistors in parallel is , however not the same. When we have to or more resistances joined in parallel to one other then the same current get additional paths to flow and the overall resistance decreases. The equivalent resistance is given by 1/Rp=1/R1 + 1/R2 +1/R3. (1)Three resistances,2 ohm , 6 ohm , 8 ohm are connected in parallel , then the equivalent resistance is(2) a wire of resistance 12 ohm is cut into 3 equal pieces and then twisted their ends together then the equivalent resistance is
