Find the magnitude of electron field which just balances a deuteron of mass `3.2 xx 10^-27 kg`. (Take g = 10 ms^-2).

Find the magnitude of electric field which will jut balance a deutron of mass 3.2 xx 10^-27 Take g = 10 ms^-2

Calculate the mass of a body weighting 100 N. Take g = 10 ms^-2 .

Calculate the electric field strength required to just support a water drop of mass 10^-7 kg and having a charge 1.6 xx 10^19C .

Determine the de-Broglie wavelength of a proton, whose kinetic energy is equal to the rest mass energy of an electron. Given that the mass of an electron is 9.1 xx 10^(-31) kg and the mass of a proton is 1,837 times as that of the electron.

The procedure in was repeated for three further oil droplets. The magnitude of the charge on each of the droplets was found to be 3.2 xx 10^-19C, 6.4 xx 10^-19C and 3.2 xx 10^-19C . Explain what value these data and your answer in would guggest for the charge on the electron.

Calculate the magnitude and direction of the electric field. Which keeps a proton just floating. Give that mass of proton 1.67 xx 10^-27 kg, charge on proton = 1.6 xx 10^-19 C and g = 9.8 ms^-2

Calcualte the ratio of the accelerating potential requied to accelrate a deutron and alpha particle to have the same de-Broglie wavelength assoiated with them.Given,mass of deutron = 3.2 xx 10^(-27) kg and mass of alpha particle = 6.4 xx 10^(-27) kg .
