Answer:
✭ Question No 1 ✭
Given :-
To Find :-
Formula Used :-
[tex]\bigstar[/tex] Moment Of Force Formula :
[tex]\mapsto \sf\boxed{\bold{\pink{\tau =\: F \times r}}}[/tex]
where,
Solution :-
Given :
According to the question by using the formula we get,
[tex]\leadsto \sf \tau =\: 10 \times 0.2[/tex]
[tex]\leadsto \sf\bold{\red{\tau =\: 2\: Nm}}[/tex]
[tex]\therefore[/tex] The moment of force is 2 Nm .

✭ Question No 2 ✭
Given :-
To Find :-
Formula Used :-
[tex]\bigstar[/tex] Pressure Formula :
[tex]\mapsto \sf\boxed{\bold{\pink{Pressure =\: \dfrac{Force}{Area}}}}[/tex]
Solution :-
Given :
According to the question by using the formula we get,
[tex]\leadsto \sf Pressure =\: \dfrac{5\cancel{00}}{1\cancel{00}}[/tex]
[tex]\leadsto \sf\bold{\red{Pressure =\: 5\: Pascal}}[/tex]
[tex]\therefore[/tex] The pressure exerted in pascal is 5 Pascal.

✭ Question No 3 ✭
Given :-
To Find :-
Formula Used :-
[tex]\bigstar[/tex] Thrust or Force Formula :
[tex]\mapsto \sf\boxed{\bold{\pink{Thrust =\: Pressure \times Area}}}[/tex]
Solution :-
First, we have to find the area :
[tex]\implies \sf Area =\: 0.5\: m \times 100\: m[/tex]
[tex]\implies \sf\bold{\purple{Area =\: 50\: m^2}}[/tex]
Now, we have to find the thrust :
Given :
According to the question by using the formula we get,
[tex]\leadsto \sf Thrust =\: 50000 \times 50[/tex]
[tex]\leadsto \sf\bold{\red{Thrust =\: 2500000\: N}}[/tex]
[tex]\therefore[/tex] The thrust will be required is 2500000 N .
