Physics Question 115 – AP-EAMCET 2025

A particle is moving with a velocity four times the velocity of an electron. If the de Broglie wavelength of the particle is $1.5\times {10}^{-4}$ times the de Broglie wavelength of the electron, then the mass of the particle is (mass of the electron $=9\times {10}^{-31}\text{ kg}$)
