Time period can be written as 2π √L/g .....so it doesn't depend on mass !

Three uniform spheres are located at the corners of an equilateral triangle. each side of the triangle has a length of 1.20 m. t
Andrei [34K]
Refer to the diagram shown below.

Because of symmetry, equal forces, F, exist between the sphere of mass m and each of the other two spheres.
The acceleration of the sphere with mass m will be vertical as shown.

The gravitational constant is G = 6.67408 x 10⁻¹¹ m³/(kg-s²)

Calculate F.
F = [ (6.67408 x 10⁻¹¹ m³/(kg-s²))*(m kg)*(2.8 kg)]/(1.2 m)²
   = 1.2977 x 10⁻¹⁰ m   N

The resultant force acting on mass m is
2Fcos(30°) = 2*(1.2977 x 10⁻¹⁰m N)*cos(30°) = 2.2477 x 10⁻¹⁰m  N

If the initial acceleration of mass m is a m/s², then
(m kg)(a m/s²) = (2.2477 x 10⁻¹⁰m N)
a = 2.2477 x 10⁻¹⁰ m/s²

Answer:
The magnitude of the acceleration on mass m is 2.25 x 10⁻¹⁰ m/s².
The direction of the acceleration is on a line that joins mass m to the midpoint of the line joining the known masses.

Explain the difference between the three types of friction
USPshnik [31]
Static Friction

It is the friction that exists between a stationary object and the surface on which it's resting.


Sliding friction

It is the resistance created by two objects sliding against each other.

Rolling friction:-

It is the force resisting the motion when a body rolls on a surface.

The frictional force exerted by the road on the body is
arlik [135]

Answer:

Explanation:

Frictional force can be defined as the force that is generated by two surfaces which are in contact with each other and even goes ahead to slide against each other. It can also be simply defined as a force that oppose the sliding of one object over the other

There are different types of frictional forces such as dry friction, lubricated friction, internal friction, fluid friction etc. One of the factors that affects frictional forces is that the forces are majorly affected by the surface texture and amount of force that bounds them together.
