Question

dimansonal formula for gravitation constant is_____________

Answer 1

G=Fxr²/m1xm2

G=gravitational force

F=gravitional force

R²=distance between two heavenly bodies like planet or star between which force have to find out.

M1 and m2- mass of first and second object respectively.

Dimension of force =M x a =MLT-²

Product of m1xm2=M²

Dimension of r²= L²

Therefore G=Fxr²/m1xm2 =MLT-² x L² /M².

= M¹xM-² x L¹xL²xT-²

=M-¹L³T-².

Answer 2

M^-1 L^3 T^-2............
