position in a gravitation field (c)
Answer:
N
Explanation:
We are given that three charged particle are placed at each corner of equilateral triangle.




Side of equilateral triangle =3.3 cm=
We know that each angle of equilateral angle=
Net force=F =
Where k=
If we bisect the angle at
then we have 30 degrees from there to either charge.
Direction of vertical force due to charge
and 
Therefore, force will be added
Vertical force=
Vertical net force=
Vertical force =
Vertical force=
(towards 
Horizontal component are opposite in direction then will b subtracted
Horizontal force=
Horizontal force=
N(towards 
Net electric force acting on particle 3 due to particle =
Net force=
Net force=
N
Answer:
Explanation:
Every chemical reaction can be represented by simple chemical equations that shows how compounds are combining to give some products.
Such reactions are usually made up of:
Reactants on the left hand side
Products on the right hand side
Reactants → Products
In this given problem;
Reactants are : Magnesium fluoride = MgF₂
Iodine in form of Iodide = I₂
Product : Magnesium iodide = MgI₂
MgF₂ + I₂ → MgI₂ + F₂
Answer:
Kinetic energy and potential energy.
The term 'mechanical energy' refers to the sum of the kinetic energy and the gravitational potential energy of an object,
