What is the value of accerelation due to gravity of the surface of the earth
Answers
Answer:
9.8 metre per second square
Explanation:
it it is actually calculated by the law of gravitational force acting between the two masses that is directly proportional to the product of masses and is inversely proportional to the square of the distance of separation between them and to eliminate the in proportionality sign put a value of capital G which is known as gravitational constant and for derivation of the value of g and a object of mass m placed on the earth placed experience a force equal to mg and equate it to the gravitational law which gives it as mg is equal to G into m into Me upon Re square where Me is the mass of earth and Re is the radius of earth and G is defined as a gravitational constant and variables have a value and m mass of the the object is cancelled out on the both side and now the values of G Me and Re used and which give the answer is 9.8 metre per second
