    T = (5 * 3) + (5 * 9.8) N = 64 N

    so option D is correct

    Explanation:

    given data

    mass = 5 kg

    acceleration = 3 m/s²

    to find out

    tension

    solution

    we know acceleration on bucket is upward so

    we say

    T - mg = ma

    here T is tension, m is mass and g is acceleration due to gravity = 9.8 m/s² and a is acceleration so

    T = ma + mg

    put here value

    T = (5 * 3) + (5 * 9.8) N = 64 N

    so option D is correct
