Gravity makes a nebula more stable in a newly formed star true or false

Before answering this question first we have to understand a nebula.

A nebula is a diffused celestial cloud of dust of gases and ionized particles like hydrogen,helium etc.

Primarily it is formed by the gas and dust which comes from a dying star during supernova explosion.

As per the question, we are asked about the role gravity. During the initial period of nebula,the particles can not bond between them to form a newly born star. Gravity plays a crucial role.Due to the high gravitational force,the particles come closer to each which increases the pressure .Now the particles are closely aggregated to each other and a new star is formed.

Hence the statement is true.

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.
