Magnitude and direction of electric fields? ?
how would you do the following? a small object a, electrically charged, creates an electric field. at a point p located 0.250m directly north of a, the field has a value of 40.0n/c directed to the south. what is the charge of object a? (a)1.11×10^-9 c (b)-1.11x10^-9 c (c)2.78x10^-10 c (d)-2.78x10^-10 c (e)5.75x10^12 c (f)-5.75x10^12 c

Abeverage can is made of 3004-h19 aluminum alloy (elastic modulus 69 gpa, tensile yield strength 285 mpa, density 2.72 g/cm^3). the dimensions on the can are approximated as a thin-walled cylinder with a height of 4.83 inches, diameter of 2.60 inches. empty the can has a mass of 14.2 g. determine: a. the wall thickness of the cylinder b. assuming a pinned-pinned condition what is the critical load? c. assuming a fixed-fixed condition what is the critical load?
