COMEDK · Physics · 9. Gravitation
Two particles, one heavy and the other light, placed at 50 cm from each other, are under the influence of gravitational force of one another. If mass of the heavier particle is 4 kg and its acceleration under the influence of gravitational force is \(5 \times 10^{-10}\ ms^{-2}\), find the mass of the lighter particle.
- A \(1.8728\) kg
- B \(3.675\) kg
- C \(7.843\) kg
- D \(0.364\) kg
Answer & Solution
Correct Answer
(A) \(1.8728\) kg
Step-by-step Solution
Detailed explanation
Let the mass of the heavier particle be \(M\) and the mass of the lighter particle be \(m\). Given: \(M = 4\) kg Distance between the particles, \(r = 50\) cm \(= 0.5\) m Acceleration of the heavier particle, \(a_M = 5 \times 10^{-10}\ ms^{-2}\) Universal gravitational constant,…

Which of the above is not true?COMEDK 2025 Easy - In Young's double slit experiment, the separation between two slits is \(0.3 \times 10^{-3} \mathrm{~m}\). When light beam is passed through the two slits, then interference pattern is observed on the screen 1.5 m away. If the first violet and red fringes are formed 2.0 mm and 3.5 mm away from the central white fringe, then the difference in wavelength of red and violet light is \(x \times 10^{-9} \mathrm{~m}\).
