Answer:
Explanation:
The motion of the electron will be periodic oscillation , ie it will go to and fro about the center of the ring. It will not be SHM as the distance at which electron has been placed is far off from the center.
Potential at the center = 9 x 10⁹ x 23.5 x 10⁻⁹ / .15
= 1410 V
Potential at distance of 30.5 cm
= 9 x 10⁹ x 23.5 x 10⁻⁹ / √ (15² +30.5²)
=9 x 10⁹ x 23.5 x 10⁻⁹ / .40
= 528.75 V
according to conservation of energy
1/2 mv² = q ( v₂ - v₁ )
1/2 x 9.1 x 10⁻³¹ x v² = (1410 - 528.75 ) x 1.6 x 10⁻¹⁹
v² = 309.9 x 10¹²
v = 17.6 x 10⁶ m /s
Let, the temperature of Sun's surface = c
So, 5c = 30, 000
c = 30,000 / 5
c = 6,000
In short, Your Answer would be 6000
Hope this helps!
Many children with congenital heart defects don't need treatment, but others do. Treatment can include medicines, catheter procedures, surgery, and heart transplants. The treatment depends on the type of the defect, how severe it is, and a child's age, size, and general health.
