Answer:
Explanation:
Given:
- Total initial charge on bead A=26 nC
- The distance between them=5 cm
- Magnitude o the force between them
Using coulombs law the force between two charged particle is 
where r is the radial distance between them
According to question we have
Hence the charge on two metal beads is calculated.
Answer: D Medium B is denser than Medium A because light bends more in Medium B.
Explanation: The more the light bends the less energy it has
Answer:
solvent: the substance in which a solute dissolves to produce a homogeneous mixture. solute: the substance that dissolves in a solvent to produce a homogeneous mixture.
Explanation:
eSo basically thats aswer
Answer: 60.0 kg*m/s north.
Explanation: The linear momentum is a verctor, it has magnitude and direction. Also the momentun is proportional to the mass multiplier the velocity.
P=m*V ( vector)
Answer:
No
Explanation:
Electric potential is the work done to bring a unit of charge (1 C) from infinity to a point inside an electric field.
Electric potential energy of a charge q is the energy required to keep it in an electric potential V. Electric potential energy is given by,
U = qV
Hence even if the two charges are on an equipotential surface (surface where the potential is the same at all points), the potenial energy will be different if the magnitude or nature of the charges are different.
