Re: ISAT Sample Questions
The Indian Institute of Space Science and Technology conducts ISAT exam. Here I am providing you the ISAT exam questions: 1. A projectile is fired at an angle 60◦ with some velocity u. If the angle is changed infinitesimally, let the corresponding fractional changes in the range and the time of flight be x and y, respectively, Then y is (A) 2 3x (B) −2 3x (C) 2x (D) −2x 2. A photon with an initial frequency 1011Hz scatters off an electron at rest. Its final frequency is 0.9×1011 Hz. The speed of the scattered electron is close to (h = 6.63×10−34 Js, me = 9.1×10−31 kg) (A) 4 × 103 ms−1 (B) 3 × 102 ms−1 (C) 2 × 106 ms−1 (D) 30ms−1 Space for rough work ET21 3/32 SETA Here I have uploaded the full paper. You can download it from here.
