In a Rutherford scattering experiment when a projectile of charge Z1 and mass M1 approaches a target nucleus of charge Z2 and mass M2, the distance of closest approach is r0. The energy of the projectile is :

Options

A. directly proportianla to `M_(1)xxM_(2)`
B. directly proportianla to `Z_(1) Z_(2)`
C. directly proportianla to `Z_(1)`
D. directly proportianla to mass `M_(1)`

Answer

B

Explanation

The energy of the projectile will be equivalent to potential energy of the charge system
`" " E=(1)/(4piepsi_(0))((Z_(1)e)(Z_(2)e))/(r_(0))rArr "Energy",EpropZ_(1)Z_(2)`
