Answer:
Explanation:
electric field = 2170 N/C
now the speed of the charge particle is given as
here we know that charge particle moves without any deviation
so we will have
now magnetic field in this region is given as
Now another charge particle enters the region with different speed and experience the force upwards
Answer: -1 or -4/4
Explanation:
4/4 simplifies to 1 and the opposite of 1 is -1.
Heat,that is when heat from fire or hot object heats
Answer:
New force = 9(initial force)
Explanation:
The force between two charges is given by :
Where
d is the original distance
Let d' is the new distance such that, r' = r/3
New force,
So, the new force becomes 9 times the initial force.
