Answer:
The right solution is "61.557 MJ". A further explanation is given below.
Explanation:
The given values are:
Force,
F = 306 N
Drive,
D = 125 miles,
i.e.,
= 201168
meters
As we know,
The work done will be:
=
On substituting the given values, we get
=
=
On converting it in "MJ", we get
=
=
Answer:
Velocity of electron will be
Explanation:
We have given distance across the plate d = 2 mm
Potential difference V = 6 volt
We know that potential difference at any distance is given by
V = Ed , here V is potential difference, E is electric field and d is distance
So
Charge on electron
We know that expression of velocity is given by , here q is charge on electron, E is electric field and d is distance
So
