20.88 mN

Explanation:

given dа ta:

mass of object = 7.2 gm

acceleration of object = 2.9 m/s2

we know that force is given as

F = ma

where m is mass of object and a is acceleration of moving object.

putting all value to get required force

= 7.2*10^{-3} / kg * 2.9 m/s2

= 20.88*10^{-3} N

force in milli newton is

= 20.88*10^{-3} * 1000 = 20.88 mN
