[
]
a) 1 Kg/m
b) 9.8 m/Sec?
c) 9.8 N d) 9.8 N/m
​

Answer 1

Explanation:

1 - the acceleration which change direction of velocity is the centripetal acceleration

2. distance between earth and moon is 3,84,400 km

3. value of universal gravitational constant is,6.67×10^-12 N.m kg2

4. weight of body = m×g

here g is acceleration due to gravity
