A force meter is used at a research station on the planet Varda.
When a test mass of 5.0 kg hangs from the force meter, the reading is 35 N.
When a canister hangs from the same force meter at the station, the reading is 21 N.
Use W=mgW=mgW=mg to calculate the gravitational field strength at the station.
Use m=Wgm=\dfrac{W}{g}m=gW to calculate the mass of the canister.
Calculate the weight of the canister on Earth, where g=10 N/kgg=10\ \text{N/kg}g=10 N/kg.
At the station, the canister is lifted off the ground by a winch cable. The cable pulls the canister upwards with a force of 27 N. The only other force on the canister is its weight.
Calculate the resultant force on the canister, giving its direction.
