A solid sphere and a ring have equal masses and equal radius of gyration. If the sphere is rotating about its diameter and ring about an axis passing through and perpendicular to its plane, then the ratio of radius is \(\sqrt{\frac{x}{2} }\) then find the value of x.
The potential energy of an electron is defined as U = \(\frac 12\) mw2x2 and follows Bohr’s law. Radius of orbit as function of n depends on? (w is same constant)
Radius of the first orbit in H-atom is \(a_0\). Then, de Broglie wavelength of electron in the third orbit is.
A particle is performing S.H.M whose distance from mean position varies as \(x = Asin(wt)\). Find the position of the particle from the mean position, where kinetic energy and potential energy is equal.
An electron is moving along positive x direction in xy plane, magnetic field points in negative z direction, then the force due to magnetic field on electron points in the direction
A particle is thrown vertically upward with initial velocity of 150m/s. Find the ratio of its speed at t=3s and t=5s. (Take g=10 \(ms^{-2}\))
Find the ratio of de-Broglie wavelength of a proton and a 𝝰 - particle, when accelerated through a potential difference of 2V and 4V respectively.
