Understanding zero electric force in electrostatics

Understand why the electric force can be zero in electrostatics by exploring charge interactions, symmetry, and superposition. This video explains the physical intuition and mathematical reasoning ...
A dead satellite can become a high-speed hazard in an orbit that is already packed with working spacecraft. That risk is why engineers at the University of Colorado Boulder are building what sounds ...
Researchers have discovered that ferroelectric fluids can harness an overlooked transverse electrostatic force (TEF) to rise over 80 mm, without magnets or high voltages. By exploiting the fluid’s ...
Ferroelectric fluids use a strong transverse electrostatic force to climb 80 mm, enabling lightweight, low-voltage motors and compact energy-efficient actuators. (Nanowerk News) Researchers have ...
The same pulling force that causes “tears” in a glass of wine also shapes embryos. It’s another example of how genes exploit mechanical forces for growth and development. Sip a glass of wine, and you ...
BUFFALO, N.Y. — Tiny solid particles – like pollutants, cloud droplets and medicine powders – form highly concentrated clusters in turbulent environments like smokestacks, clouds and pharmaceutical ...

Local governments across Florida are beginning to work alongside the U.S. Immigration and Customs Enforcement to train local law enforcement to identify and remove criminal immigrants. The goal of the ...
At least 400 people have been killed in northwest Syria after days of clashes between government forces and loyalists of former President Bashar al-Assad marked the deadliest violence since the fall ...
If you took introductory physics, you learned about the “fundamental forces.” It goes something like this: All interactions are the result of one or more of five basic forces: strong nuclear, weak ...
