Three 3 kg masses are located at points in the xy plane. 36 cm 52 cm What is the magnitude of the resultant force (caused by the other two masses) on the mass at the origin? The universal gravita- tional constant is 6.6726 × 10−11 N · m2/kg2. Answer in units of N.

5.136 is the magnitude of the resultant force (caused by the other two masses) on the mass at the origin

Explanation:

Use Newton's law of gravitation

G - gravitational force

m -mass of the object

(vertical force):

(horizontal force):

hence F on the mass of origin

a small object of mass 3.66 g and charge -17.6 µc is suspended motionless above the ground when immersed in a uniform electric field perpendicular to the ground. what are the magnitude and direction of the electric field?

a

explanation:

no diagram was provided, but i'm guessing it's the one i've attached to my answer.

here, a mechanical force turns the rod.   this generates an electric current in the coil, which powers the bulb.
