Question

a small particles carrying a negative charge of 1.56*10^-19 is surrounded by equilibrium between the horizontal metal plates 5cm apart having a potential difference of 3000 across them. find the mass of the particles​

Answer 1

Answer:

E = - dv / dr

= -3000 / 5 × 10^-2

mg = qE

m × 9.8 = 1.56 × 10^-19 × ( -3000 / 5 × 10^-2)

m = 9.8 × 10^-16 kg
