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

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.
