If there is an attractive force between all objects, why do we not feel ourselves gravitating toward massive buildings in our vicinity ?

Why do we feel thirsty?

Why do we feel more diffraction in sound wave than in light wave?

Why do we call our heart myogenic?

Due to which force all objects fall towards earth?

The sun and the earth both exert a gravitational force of attraction on any object on the earth's surface. The two gravitational forces are in opposite directions during noon and in the same direction at midnight. Will an object weight more at midnight ?

The electrostatic force between two point charges and the gravitational attractive force between two point masses- both are inversely proportional to the square of the distance between the charges and the masses, respectively. (1)(a) Compare the eletrostatic force (F_(C)) and the gravitational force (F_(G)) between an electron and a proton. (b) Compare F_(C) and F_(G) between two protons. (ii) Find out the accelerations of an electron and of a proton due to the electrostatic force between them when htey are placed at a distance of 1 Å

Coulomb’s law for electrostatic force between two point charges and Newton’s Law of gravitational force between masses depends on the distance between the charges/ masses. (b) Estimate the accelerations of electron and proton due to the electrical force of their mutual attraction when they are 1overset@A(=10^(-10)m) apart? (m_p=1.67x10^(-27)kg,m_e=9.11x10^(-31)kg)

State whether True or False : The force with which sun attracts an object near it is called gravitational force.

State whether True or False : The force with which earth attracts an object near it is called gravitational force.
