Answer:
Explanation:
Given
for 
Sphere are 
when sphere
apart suppose deflection is 
We know

Where F=force between charged particle
Deflection


thus 
for 



(b)for
deflection Potential 
Electric Potential is 

where V=voltage
k=constant
r=distance between charges
Put value of Q in equation 1


thus 
therefore



Answer:
B=4.343 * 10⁻⁵ T
Explanation:
See attached photo for explanation.
I think the correct answer is A mark has greater gravitational potential energy
:)
Answer:
100 m
Explanation:
pressure in fluid is given by multiplying height, density and acceleration due to gravity. Taking acceleration due to gravity as 10 then
10*h*1000=100000
h= 100000/10000=100 m
Therefore, the height is approximately 100 m
