So you're absolutely right. It is the derivative of the given eqn. thus getting -6C_6/x^7
And considering atoms are neutral and give off no outward magnetism, they apply a really small attractive force on each other [will have to check but i think it's due to gravity, not sure. but it's...
The centripetal force Fc, for a body of mass m traveling with speed v in a circle of radius r is,
Fc = (mv^2)/r....eqn 1
The object to slip off the turntable if the centripetal force overcomes the maximum force due to static friction F_max:
F_s = (u_s)N = (u_s)mg...eqn 2
u_s is...
First off
@hallsofivy: dude that's so retarded. he already squared it it's (3mm)^2 which becomes 9mm squared.
Final answer: your answer is in fact right you're only off by a degree of 10^-3. such that the final answer should be 4.69*10^-4. I think this happened when you were converting...
