Answer:
Explanation:
Given
Dimension of Plastic sheet is
Charge on sheet
Charge density
Sphere has mass of
If sphere is suspended motionless then its weight is balanced by repulsion force
Repulsive force
where E=Electric field due to sheet
Explanation:
It is given that,
Velocity of the electron,
Magnetic field,
Charge of electron,
(a) Let is the force on the electron due to the magnetic field. The magnetic force acting on it is given by :
(b) The charge of electron,
The force acting on the proton is same as force on electron but in opposite direction i.e (-k). Hence, this is the required solution.
I think the answer would be Electrons. The process of chemical reactions transfer or share electrons that creates an attraction which hold the atoms together.
Answer:
a) , b) , ,
Explanation:
a) The system mass-spring is well described by the following equation of equilibrium:
After some handling in physical and mathematical definition, the following non-homogeneous second-order linear differential equation:
The solution of this equation is:
The velocity function is:
Initial conditions are:
Equations at are:
The spring constant is:
After some algebraic handling, amplitude and phase angle are found:
The position can be described by this function:
b) The period of the motion is:
The amplitude is:
The phase of the motion is:
Answer:
equal to the force of gravity, F= mg
