# What is d pressure in empty space? in atm and solve using standard value?

1. compare d electrostatic replusive force btw 2 electrons with attractive force due to gravitation by finding d ratio of d magnitude of d force 2. three similar charges: +8.5uC are situated at d corners of and equilateral triangle of side 10cm calc d force on each charge in magnitude and direction.

There is no repulsion between electrons unless they come close to each other in a certain proximity.

The gravity pressure of space on a electron is equal to the mass of the electron times the speed of light squared divided by the volume of the electron mass.

empty space has no medium, so its pressure will be zero.

1. electric force Fe / gravitational force Fg = 10^42 (after using relevant values)

2. force on any one fo the charges F = square root of 3 x 9x10^9 q / a^2,

where q = 8.5x10^-6 C and a = side = 0.1 m

hence, F = 7.65 x 10^6 N. its direction will be normal to any one corner along the biscetor of the triangle.

You'll be able use the card in any Link machine without paying charges. You will certainly be able to use machines provided by other banks but some will charge. There has been a general trend in the UK away from charging for ATM transactions but unless there is a notice on the machine that clearly states you won't be charged it's probably safer to assume you will. You can also use the card around the world in any ATM displaying the Visa symbol, but you will be charged a cash advance fee.
