The increasing order (lowest first) for the values of e / m (charge/ma...
The e/m ratio is known as specific charge where, e is the charge on particle and m is mass of the particles.
For neutrons ⇒ charge is zero.
mass =1.6×10−27 amu
For proton ⇒ charge =1.6×10−19C
mass =1.6×10−27 amu
For electron ⇒ charge =1.6×10−19C
mass =9.1×10−31 amu
For α−particle ⇒ charge ⇒2×1.6×10−19C
mass ⇒4×1.6×10−27 amu
From these data, it can be concluded that neutron has least (e/m) specific charge and electron has highest.
correct option is (d)
