Explanation:
Formula for the electric field due to the infinite sheet of charge is as follows.
E =
where, = surface charge density
Now, formula for electric force acting on the proton is as follows.
F = eE
where, e = charge of the proton
According to the Newton's second law of motion, the net force acting on the proton is as follows.
F = ma
a =
=
=
According to the kinematic equation, speed of the proton in perpendicular direction is as follows.
=
=
= 683.974 m/s
Hence, total speed of the proton is as follows.
v' =
=
=
= 1178.73 m/s
Therefore, we can conclude that speed of the proton is 1178.73 m/s.
Answer:
Explanation:
The force of gravity acting on the satellite is given by:
where
G is the gravitational constant
is the Earth's mass
m is the mass of the satellite
r is the distance of the satellite from the Earth's centre
Here we have
m = 700 kg
Substituting into the equation, we find:
<em>Note that the distance mentioned in the problem (2.4 x 10^6 meters) is not realistic, since it is less than the radius of the Earth (6.37 x 10^6 meters).</em>
