Three charged particles are initially in position `1`, "They are free to move and they come in position" `2` "after some time. Let" `U_(1)` and `U_(2)` be the electrostatic potential energies in position `1 and 2`. Then

A charge particle q_(1) , is at position (2, -1, 3). The electrostatic force on another charged particle q_(2) at (0, 0, 0) is :

A charge particle q_(1) , is at position (2, -1, 3). The electrostatic force on another charged particle q_(2) at (0, 0, 0) is :

A particle moves with simple harmonic motion in a straight line. When the distances of the particle from the equilibrium position are x_(1) and x_(2) , the corresponding velocities are u_(1) and u_(2) . Find the period of the moton.

A particle is moving in SHM in a straight line. When the distance of the particle from equilibrium position has values x_(1) and x_(2) , the corresponding values of velocities are u_(1) and u_(2) . Show that time period of vibration is T=2pi[(x_(2)^(2)-x_(1)^(2))/(u_(1)^(2)-u_(2)^(2))]^(1//2)

The potential energy of a particle oscillating on x-axis is given as U +20 +(x-2)^(2) . The mean position is at

A particle free to move along x-axis is acted upon by a force F=-ax+bx^(2) whrte a and b are positive constants. For ximplies0 , the correct variation of potential energy function U(x) is best represented by.
