The electric force due to a uniform external electric field causes a torque of magnitude 16.0 ×× 10−9−9 N⋅mN⋅m on an electric dipole oriented at 30∘∘ from the direction of the external field. The dipole moment of the dipole is 8.5 ×× 10−12−12 C⋅mC⋅m. What is the magnitude of the external electric field? If the two particles that make up the dipole are 2.5 mm apart, what is the magnitude of the charge on each particle?

Organelles are 1. responsible for producing power for the cell 2. tiny structures in the cell that carry out the cell's activities 3. responsible for digestion in the cell 4. found outside of the membrane

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?
