    M-How to calculate force on a surface due to a beam of particles?

    thanks..so do i need to know the mass of a helium atom to answer this question? so far iv said: the change in momentutm = (3.0*10^7)(mass of he atom)(sin60)(2)=5.1961*10^7(mass of he atom) according to my book the rate of change of momentum= (z component of momentum)( z component of...
