Answer:
\frac{R}{^{\sqrt{2}}}
Explanation:
q1 = q , q2 = q
m1 = M, m2 = 2M
Potential difference is V
Let v1 be the speed of first particle and v2 be the speed of second particle.
Energy due to potential difference gives the kinetic energy to the particle.
1/2 m x v^2 = e V
v^2 = 2 e V / m = 2e V / m ... (1)
Now radius is given by
r = m v / B q
by eqution (1)
For first particle
.... (2)
For second particle
.... (3)
Divide equation (2) by equation (3), we get
So
r1 / r2 =
The right answer is true because particles are allowed to freely move in gases but in liquids the particles can not leave the other particles, they may move freely but with other particles but gas particles can be found individually roaming around
She feel warm due to sun shining on her back which shows the transfer of energy due to Radiation Mode of heat transfer.
Because in this case we do not need any medium to transfer the heat and all energy is transferred due to electromagnetic waves.
She feels warm sand under her feet which shows the heat transfer due to conduction mode.
Because in this mode of heat transfer the heat is transmitted by direct contact.
A cool breeze is blowing from the water which shows the heat transfer due to convection mode.
Here thermal energy is being transferred by the moving medium molecules.
