ProtonVPN was first launched in June of 2017 as an add-on to the popularsecure email service Proton Mail. Although best known for its strict privacy controls and the fact that they own many of their own servers, for the sake of this writeup it’s good to know that they have the best...
What is the mass number of a proton? What is the charge, in Units of the electronic charge, of a proton. Express your answer as an integer. What is the positive ion and its charge? What is the charge of Pb? An atom has 75 protons, 74 electrons, and 112 neutrons. What is the ch...
The force acts in a side ways direction perpendicular to both the velocity and magnetic field and the direction is given by right hand thumb rule for vector product. Obviously force on a negative charge is opposite to that on a positive charge. When will a moving charge experience maximum ...

What is the total positive charge in 200 g of water? Atomic Number: The atomic number of an element gives us the number of the proton or positive charges present in the nucleus of the atom. Answer and Explanation: Given: The mass of water is m = 200 g. The molecular mass of...
atomic nucleus, the proton will exchange a meson at the extremely quick speed with neutron, the son will turn into a proton while losing a meson, will turn into a neutron when the proton get a meson among them. No doubt, it is positive charge that is exchanged. Because proton exchange ...
