Ok I've got to the point where I've found that the components of N (the normal reaction force) are: N sin x and N cos x I don't study maths so could you please give me hints as to how I turn the above into F = W tan x?

Hey...i need help... "One practical arrangement for verifying Coulomb's law is to use a lightweight, negatively charged, freely-suspended ball. it is repelled by the negative charge on a larger sphere that is held near it, on an insulated support. the small angle of deflection, x is then...

ok I am off back to grade school

ohh so: m3 kg s-2? and how do you make those lovely italic expressions? :)

i don't knoww! i mentioned i was **** at doing these things in my first post! somebody please just tell me how to do it! this is in for tmoro!

units of a Newton are m kg s-2

i think i worked it out... could anyone clarify if the correct base units are : kg m² sˉ²

Hi. Part of my homework was to work out what the SI base units of the gravitaional constant are. I'm crap at working out base units so could somebody help me out? Thanks If anyones wondering, G is 6.67 x 10ˉ¹¹ N m² kgˉ²
