<span>Let L and R be the left and right vertical floor reactions
let T be the tension of the rope
summation of all forces is zero
R + L - 500 - 150- 150 = 0
R + L = 800
since the triangle formed is isosceles triangles, the legs are equal
R = L = 400 N
using the summation of the torque
L [ 4] - T[ 3 - (2 *3/5)] = 0
400 [ 4] - T[ 1.8] = 0
T = 1600/1.8
T = 889 N </span>
Explanation:
The acceleration on an object due to the gravity of any massive body is represented by g (small g). The force of attraction between any two unit masses separated by unit distance is called universal gravitational constant denoted by G(capital g). The relation between G and g is not proportional. That means they are independent entities.
G and g
In physics, G and g can be related mathematically as –
\(g=\frac{GM}{R^{2}}\)
Where,
1=g is the acceleration due to the gravity of any massive body measured in m/s2.
2=G is the universal gravitational constant measured in Nm2/kg2.
3=R is the radius of the massive body measured in km.
4=M is the mass of the massive body measured in Kg.
The rock will sink.
The density of water is 1.0g/cm^3
The density of the rock is 1.73g/cm^3
