Question
A metal sphere hangs from a string and has 6 kg of mass. The sphere has a charge of +3.3 C. A uniform electric field is turned on and directed to the right.
A) What is the electric force on the metal sphere if the magnitude of the electric field is 106 N/C?
B) When the sphere reaches equilibrium, what is the angle that the string makes with the vertical axis (assuming the same electric field as part (a)?
A metal sphere hangs from a string and has 6 kg of mass. The sphere has a charge of +3.3 mu C. A uniform electric field is turned on and directed to the right. What is the electric force on the metal sphere if the magnitude of the electric field is 106 N/C? When the sphere reaches equilibrium, what is the angle that the string makes with the vertical axis (assuming the same electric field as part (a)?Explanation / Answer
A) F = q*E = 3.3 N
B)theta = tan^-1(q*E/m*g) = 3.21 degrees
