A uniform magnetic field of 30 m T exists in the X direction.A particle of charge `+1.6xx10^(-19) C` and mass `1.67xx10^(-27)` kg is projected through the field in the +y direction with a speed of `4.8xx10^6 m//s`.
Find the force on the charge particle in magnitude and direction.

The uncertainty in position and velocity of a particle are 1.0xx10^(-5) m and 4.28xx10^(-20)m*s^(-1) respectively. Calculate the mass of the particle.

The uncertainties in posiiton and velocity of a particle are 10^(-10) m and 5.27xx10^(-24)m*s^(-1) respectively. Calculate the mass of the particle.

The velocity of a proton is 10^3 ms^-1 and mass of it is 1.67 xx10^(-27) kg , determine the Wavelength of that proton particle in nanometer unit (h = 6.63 xx 10^(-34) Js)

Two charges 2.0xx10^(-6)C and 1.0xx10^(-6)C are placed at a separation of 10 cm. Where should a third charge be placed such that it experiences no net force due to these charges?

A proton obliquely enters a uniform magnetic field of 0.5 T. It the component of its velocity along and perpendicular to the direction of the magnetic field are 1.5xx10^(5)m.s^(-1) and 2xx10^(5)m.s^(-1) , respectively, calculate the radius of the helical path followed by the proton ant its pitch.
