Gravitation question

2025 · 3 Apr · Shift 1 · Q74

JEE MainPhysicsGravitationNumerical+4 / −1
Three identical spheres of mass m , are placed at the vertices of an equilateral triangle of length aaa. When released, they interact only through gravitational force and collide after a time T=4\mathrm{T}=4T=4 seconds. If the sides of the triangle are increased to length 2a2 a2a and also the masses of the spheres are made 2 m , then they will collide after ‾\underline{\hspace{2cm}}​ seconds.
