Two charges q1=−17C and q2=6C are positioned at different coordinates as shown in the figure. Coordinate of q1 charge is (b, a) and that of q2 charge is (−b, a) . Find the net electric field at the origin in unit vector notation . Assume that a=2m and b=7m . Here C denotes coulombs and m denotes meters.

Mass / weighthope it !

Stars are born within the clouds of dust and scattered throughout most galaxies. a familiar example of such as a dust cloud is the orion nebula. turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. as the cloud collapses, the material at the center begins to heat up. known as a protostar, it is this hot core at the heart of the collapsing cloud that will one day become a star. three-dimensional computer models of star formation predict that the spinning clouds of collapsing gas and dust may break up into two or three blobs; this would explain why the majority the stars in the milky way are paired or in groups of multiple stars.therefor, i would say the answer is: dust and gases contract.i hope this ! < 3
