Answer:
m' = 1 x 10⁻⁶ kg/s
Explanation:
Given that
Diffussion constant = 1 x 10⁻¹¹
Mass flow rate ,m = 2 x 10⁻⁶ kg/s
The diffusion is inversely proportional to the thickness of the membrane and therefore when the thickness is doubled, the mass flow rate would become half.
So new flow rate m'
m' = 1 x 10⁻⁶ kg/s
Answer:
2.08 x 10⁻⁶ T
Explanation:
= velocity of electron = 5.0 x 10⁷ m/s
q = charge on electron
B = magnetic field = ?
E = electric field = 104 V/m
Magnetic force on the electron is given as
Electric force on the electron is given as
For the electron to pass without being deflected, we must have
(5.0 x 10⁷) B = 104
B = 2.08 x 10⁻⁶ T
