Answer:
There is an attractive force between the rod and sphere.
Explanation:
When negatively charged rod is placed close to the metal sphere then due to the electric field of the rod the opposite free charge of metal sphere comes closer to the rod on one surface
While similar charge in the metal sphere move away from the rod due to repulsion of electric field of rod
This temporary charge distribution of the metal sphere is known as induction
And since opposite charge on the metal surface comes closer to the metal sphere so here we can say that the rod will attract the metal sphere
so here correct answer will be
There is an attractive force between the rod and sphere.
Answer:
Same

The answer is A. for every action there is an equal and opposite reaction
A piece of wood is has a density of 0.6 g/cm3. when dipped in olive oil of density 0.8 g/cm3, 0.75 fractions of the wood is submerged inside the oil.
Fractions describe any number of parts of a whole, or more generally equal parts.In everyday English, fractions describe how many parts of a particular size there are. 8, 3/4.
In mathematics, fractions are used to represent proportions/parts of a whole. represent the same part of the whole. A fraction has two parts, a numerator and a denominator. The top number is called the numerator and the bottom number is called the denominator. A fraction is a part of a whole number and a way of dividing a number into equal parts. It is described as the number of equal parts counted (called the numerator) to the number of whole parts called the denominator. These numbers are separated by dashes.
