Answer:
Weight on Jupiter will be equal to 2940 N
Explanation:
We have given given acceleration due to gravity on Jupiter is 3 times of acceleration due to gravity on earth
Acceleration due to gravity on earth 
So acceleration due to gravity on Jupiter = 
Mass is given m = 100 kg
We have to find the weight
Weight is equal to W = mg, here m is mass and a is acceleration
So weight 
True is the correct answer
