In Thomson's experiment if the value of q/m is the same for all positive ions striking the photographic plate, then the trace would be

A beam of singly ionized atoms of carbon (each charge +e) all have the same speed enters a mass spectrometer, as shown in Fig. The ions strike the photographic plate in two different locations 5 cm apart. The ._12C_6 isotope traces a path of smaller radius, 15.0 cm . What is the atomic mass number of other isotope ? .

All the particles thrown with same initial velocity would strike the ground. .

If the expression (m x-1+(1//x)) is non-negative for all positive real x , then the minimum value of m must be

If the expression [m x-1+(1/x)] is non-negative for all positive real x , then the minimum value of m must be

In Thomson's experiment for determining e//m the potential different between the cathod and the anod (in accelerating coloumns ) is same as that between the deflecting plates (in the regions of crossed field ) . If the p.d is doubled , by what factor should the magnetic field be increased to ensure that the electron beam remains undeflected
