The dimension of universal gravitational constant is???.?

The dimension of the universal gravitational constant, denoted by G, is M^(-1)L^(3)T^(-2). To understand the meaning of each symbol, let's break down the dimensions. M represents mass, L represents length, and T represents time. The exponent of each symbol represents the power to which it is raised. For example, M^(-1) means the inverse of mass, or mass to the power of negative one. Therefore, M^(-1)L^(3)T^(-2) means that G has units of mass raised to the power of negative one, length raised to the power of three, and time raised to the power of negative two. In simpler terms, this means that G is a constant that relates the gravitational force between two objects to their masses, the distance between them, and the amount of time that has passed. It tells us how strong the force of gravity is between two objects of a given mass and distance. So, the correct option is the first one: M^(-1)L^(3)T^(-2).
