The answer is number 2 :)
Answer:
Kepler's third law of planetary motion
Explanation:
Kepler's third law of motion gives the relationship between a planet’s distance from the sun and the amount of time it takes the planet to orbit the sun. Its formula is given by :
Where
T is the time taken by the planet to orbit the sun
M is the mass of sun
G is the universal gravitational constant
a is the distance of planet form the sun
No.
If they add together to get a vector of length zero they should make a triangle of loading.
The sides 1 m, 2 m and 4 m will not make a triangle since the sum of 1 and 2 is less than 4.
In the given figure a+b < c , so they make a triangle.
Here this condition is not satisfied.
Field at the center is zero because net electric field on the surface is same.
