Answer:
Explanation:
The electric field is generated by a charge and represents the force exerted on a test charge, that is, the electric force per unit of charge. Therefore the equation for the electric field can be obtained from Coulomb's law.
Answer:
It spreads out into multiple shadow regions
Explanation:
- when the waves meet the barrier than light is diffracted as When this occurs, the wave bends around the corners of the barrier or passes through the opening of the wedge, which acts as a barrier, forming several patterns with the hole shape of the wedge.
- and The main condition for this phenomenon to occur is that the magnitude of the barrier must be equal to the magnitude of the wavelength.
- when sunlight as an electromagnetic waves is passes by key hole of gate, then this light will break and form many keyhole-shaped shadow fields.
magnitude of the net force = mass x acceleraton
= 22 x 2.3
=50.6 N
