Answer:
Explanation:
THE GIVEN sheet can be taken as two horizontal force with surface charge density is
at one surface is ∈_1 =
at oher surface is ∈_2=
the magnitude of electric field due to surface charge is given as
So, electric field at P (2 CM below from surface is) = E_1 +E_2
Answer:
Explanation:
From the question we are told that:
First Mass
2nd Mass
Distance
Generally the Newtons equation for Gravitational force is mathematically given by
Therefore
Initial force on m
Final force on m
Acceleration of m
Answer:A)0.5 and 2 mm
Explanation:
Given
radius R of wire is 1 mm
magnetic Field at edge(surface)
Magnetic Field at a distance r' from Center is
and we know
where
Permeability of free space
distance from center
For
---1
For
---2
Divide 1 and 2
If r is inside the wire then
for
---3
for
----4
Divide 3 and 4
If the mass of one of the objects is tripled, then the force of gravity between them is tripled. ... Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.
Answer:
B)5.52x10^9 J
Explanation:
The equation for calculating kinetic energy is as follows
E=
so what we have to do is calculate the kinetic energy of the space probe in each state and calculate the difference
E=
E=
E=(1500)(5000^2-4200^2)/2
E=5.52x10^9 J
