3 su'aalood oo ku saabsan isle'egta cufisjiidadka
1. Saddex qaybood oo midkiiba miisaankoodu yahay 1 kg ayaa ku yaal geesaha saddexagal siman oo dhinacyadu ay dhererkoodu yahay 1 m. Waa immisa xoogga cufisjiidadka ee ay la kulmaan walax kasta oo dhibic ah (G)?
Solution
Cabbirka xoogga cufisjiidadka ee uu la kulmo mid ka mid ah walxaha.
F 12 = G (m 1 )(m 2 ) / r 2 = G (1)(1) / 1 2 = G/1 = G
F 13 = G (m 1 )(m 3 ) / r 2 = G (1)(1) / 1 2 = G/1 = G
