Answer:
Explanation:
We know that at pointed corner of a conductor , charge accumulate ie electric field is maximum . Ar pointed corner , radius of curvature will be least . That is why charge leakage is greatest at pointed corner of a charged conductor.
a ) Electric field will be 26.0 kN/C at the point where radius of curvature is greatest .
b ) So electric field will be 66 kN /C at the point where radius of curvature is smallest .
Answer:
Stars live to long to be observed from birth to death
Explanation:
The life expectancy of a star are millions of years compared to that of human thereby making it difficult to study the life path and activities of the stars till the point of extinction. This brought about scientist studying different star with different ages in order to answer their burning question on formation of stars which is called the figuring out process(stellar activity) and this makes it difficult and tedious.
