Consider a spherical homogeneous cloud of mass M made by an explosion. Due to energy received from the explosion, it is expanding and the expansion is spherically symmertric. At an instant its radius is R and all the particle on the surface are moving away from its center with velocity v₁. What would be its radius when expansion ceases (At every instant, density of cloud remain homogeneous)):- (1) GMR0/2GM-R0BV0^2 (2) 2GMR0/2GM-R0V0^2 (3) GMR0/2GM+R0V0^2 (4) None of these
