Two masses m and M are attached to the strings as shown in the figure. If the system is in equilibrium, then View Solution A particle of mass m and charge q is fastened to one end of a string of length. The other end of the string is fixed to the point O. The whole sytem liles...
Two particles of mass m each are tied at the ends of a light string of length 2a. The whole system is kept on a frictionless horizontal surface with the string held tight so that each mass is at a distance a from the centre P (as shown in the figure). Now, the mid-point of the...

Answer to: If the mass of two particles is 2 grams each then when they combine to form a nucleus how much will be the mass of the nucleus? By...
(5) where , , and are four different three-dimensional unit vectors determining four spatial directions, along which the spins of the two particles can be measured. In order to test this (generalized) Bell inequality one needs to maximize the left-hand side of (5) by a suitable choice ...
The BEC are measured for pairs of like-sign charged particles, each with |η| < 2.5, for two kinematic ranges: the first with particle pT > 100 MeV and the second with particle pT > 500 MeV. The BEC parameters, charac- terizing the source radius and particle correlation strength, are ...
Active matter has been much studied for its intriguing properties such as collective motion, motility-induced phase separation and giant fluctuations. However, it has remained unclear how the states of active materials connect with the equilibrium phases
We study a system of active particles with soft repulsive interactions that lead to an active cluster-crystal phase in two dimensions. We use two different modelizations of the active force - Active Brownian particles (ABP) and Ornstein-Uhlenbeck particles (AOUP) - and focus on analogies and ...
Three particle each of mass m are placed at the corners of equilateral triangle of side l Which of the following is/are correct ? View Solution Three particles each of massmare kept at the vertices of an euilateral triangle of sideL. The gravitational field at the centre due to these parti...
