Answer:
Answer:
6.68 x 10^16 m/s^2
Explanation:
Electric field, E = 3.8 x 10^5 N/C
charge of electron, q = 1.6 x 10^-19 C
mass of electron, m = 9.1 x 10^-31 kg
Let a be the acceleration of the electron.
The force due to electric field on electron is
F = q E
where q be the charge of electron and E be the electric field
F = 1.6 x 10^-19 x 3.8 x 10^5
F = 6.08 x 10^-14 N
According to Newton's second law
Force = mass x acceleration
6.08 x 10^-14 = 9.1 x 10^-31 x a
a = 6.68 x 10^16 m/s^2
Explanation:
Answer:
Explanation:
Assuming motion of equation of SHM as
where,
t=time
thus velocity at any Point x is given by
when speed is 50 % of its maximum value
(b)When Potential Energy is 50 % of total energy
Total Energy
potential energy at any x is given by
Density: 1.9 g/cm3
density = mass/volume
d = 5.7/3
d = 1.9
S=ut+a(t^2)/2 = a(t^2)/2 [since u=0] =(v/t)*(t^2)/2 [since a=(v-u)/t=v/t] =vt/2 =180*{25/(60*60)}/2 km = 0.625 km =625 m
