Explanation:
It is given that,
Kinetic energy of the electron,
Let the east direction is +x direction, north direction is +y direction and vertical direction is +z direction.
The magnetic field in north direction,
The magnetic field in west direction,
The magnetic field in vertical direction,
Magnetic field,
Firstly calculating the velocity of the electron using the kinetic energy formulas as :
(as it is moving from west to east)
The force acting on the charged particle in the magnetic field is given by :
Since,
And,
(b) Let a is the acceleration of the electron. It can be calculated as :
Hence, this is the required solution.
Answer:
a)
b)
c)
d) Treat the humans as though they were points or uniform-density spheres.
Explanation:
Given:
- mass of Mars,
- radius of the Mars,
- mass of human,
a)
Gravitation force exerted by the Mars on the human body:
where:
= gravitational constant
b)
The magnitude of the gravitational force exerted by the human on Mars is equal to the force by the Mars on human.
c)
When a similar person of the same mass is standing at a distance of 4 meters:
d)
The gravitational constant is a universal value and it remains constant in the Universe and does not depends on the size of the mass.
- Yes, we have to treat Mars as spherically symmetric so that its center of mass is at its geometric center.
- Yes, we also have to ignore the effect of sun, but as asked in the question we have to calculate the gravitational force only due to one body on another specific body which does not brings sun into picture of the consideration.
