begin mathsize 14px style Given colon Diameter space of space straight P subscript 2 equals 50 space cm Diameter space of space straight P subscript 1 equals 10 space cm Force space on space straight P subscript 1 comma space straight F subscript 1 equals 1 space straight N Pressure equals Force over Area Pistons space straight P subscript 1 space and space straight P subscript 2 space are space hydraulically space coupled. According space to space the space Pascal apostrophe straight s space law comma space the space pressure space exerted space to space the space working space fluid space must space be space equal space for space both space the space pistons. For space 1 st space piston comma space straight P subscript 1 equals straight F subscript 1 over straight A subscript 1 For space 2 nd space piston comma space straight P subscript 2 equals straight F subscript 2 over straight A subscript 2 end style
Syntax error from line 1 column 89 to line 1 column 130. Unexpected 'mathvariant'.
 
Therefore, the force exerted on P2 is 25 N.
