What is the minimum energy required to launch a satellite of mass m from the surface of a planet of mass M and radius R in a circular orbit at an altitude of 2R? Total energy E=1/2mv^(2)-(GmM)/r =(GmM)/(2r)-(GMm)/r=-G(mM)/(2r) r=2R=R=3R E=(GmM)/(6R) Potential energy =-(GMm)/R Minimum energy required =1/6(GMm)/R-((-GMm)/R)=5/6(GMm)/R

Subjects in the Science Stream after Completing 10th Grade. The Science stream is divided into medical (PCB) and Non-medical (PCM). The distinction between the two is in the third subject chosen. In other words, while medical and non-medical students must take Physics, Chemistry, and Mathematics, the medical stream requires Biology as a third.

Solution i = 3/4 A for minimum deviation we know, A + δ m = 2i Therefore, A + δ m = 2 × 3/4 A δ m = (1.5 − 1)A ⇒ δ m = 0.5 A For equilateral prism A = 60°. (i) ⇒ δ m = 0.5 × 60° = 30°. (ii) Also, for minimum deviation, refractive index of glass w.r.t. air is given by
