Answer:
Explanation:
A point charge of +2q centered in a conductive spherical shell of inner diameter a and outer diameter b will induce - 2q charge on the inner surface and +2q charge on the outer surface of the shell. Since 8q charge has been added to the shell , this charge will reside on the outer surface of the shell. so total charge on the outer surface will be 10q. At a point less than a , the electric field will be due to +2q charge situated at the centre . The electric field will be as follows
E = k .2q / r² for r < a
= 8kq/ a²
electric field at a point r = a>b
total charge lying inside is +2q - 2q = 0 . So in the thickness of the shell , electric field will be zero as total charge inside is nil.
For a point at r > b total charge inside is 2q-2q+10q = 10q , so electric field at r which is lying outside the shell .
E = k 10 q / r² for r > b
Answer:
Explanation:
T = 2π√(L/g)
If you increase L to 2L, the period is increased by a factor of √2
T = 3.5√2 ≈ 4.9 s
The North America will not be able to view the eclipse because of its location on the earth caused by the tilting of the earth.
<h3>
Effect of tilting of the Earth</h3>
The tilt of the Earth is what causes seasons to occur. These are the seasons in relation to the Northern Hemisphere.
The tilting of the Earth causes the difference in the amount of sun reaching each region of the earth like in the North America continent.
Thus, the North America will not be able to view the eclipse because of its location on the earth caused by the tilting of the earth.
