    Force = - 2.1 Newton

    Step-by-step explanation:

    According to question,

    The value of Spring constant, K = 7 N/m Newton per meter

    And the spring is extended up to 0.3 meter

    The Force experience on the spring is calculated from the Hook's Law

    The principal state that, the force applied on spring to extend or compress the spring to some distance is proportion to that distance.

    Let the force be F

    So, F = - K X

    where K is spring constant and X is its displacement

    Negative sign shows displacement of spring once it is stretched

    And K is spring constant

    So, Force = (-) 7 * 0.3

    I. e Force = - 2.1 Newton Answer
