Answer:
e) upwrad z axis
Explanation:
To know the direction of the force we use the right hand rule.
The thumb points in the direction of the velocity, the fingers extended in the direction of the magnetic field and the palm of the hand in the direction of the force, this is for a positive charge if the charge is negative the force is in the opposite direction of The palm of the hand.
Let's apply to our case.
The thumb is in the x direction, the fingers in the vertical direction and since the electron has a negative charge, the force is on the z axis (perpendicular to the blade, coming out)
In general, in the nomenclature of the cardinal points the positive x-axis is the East, the positive y-axis is the North. Therefore the answer must be up on the z axis
I believe the answer is A.
(0.5)×(0squared)×(3)=(1.5j)
Answer:
radio waves, micro wave, x-rays
Explanation:
The gravitational force of attraction between two objects is directly proportional to the product of the two masses and inversely proportional to the square of the distance between them.
Where,
G = Gravitational Universal Constant
M = Mass of the Planet
m = Mass of the object
r = Distance
Therefore the amount of force exerted by the first object on the second object is equal to the amount of the force exerted on the second object by the first.
The gravitational force exerted by Larry on the Earth is same as the force exerted on Larry by the Earth.
That is 300N.
