List of top Chemistry Questions on Quantum Mechanics asked in JEE Main

Two positively charged particles are accelerated by \(200\,\text{keV}\). The masses of particles are \(m_1 = 1\,\text{amu}\) and \(m_2 = 4\,\text{amu}\).
If the de-Broglie wavelength \((\lambda_d)_{m_1}\) is \(x\) times of the second particle \((\lambda_d)_{m_2}\), determine the value of \(x\).

Given below are two statements:
Statement (I): It is impossible to specify simultaneously with arbitrary precision, the linear momentum and the position of a particle.
Statement (II): If the uncertainty in the measurement of position and uncertainty in measurement of momentum are equal for an electron, then the uncertainty in the measurement of velocity is \( \geq \sqrt{\frac{h}{\pi}} \times \frac{1}{2m} \).
In the light of the above statements, choose the correct answer from the options given below:
