Answer:

The work done is 20 Joules (J).

Step-by-step explanation:

To calculate the work done, we can use the formula:

Work = Force dot Displacement

Given the force vector F = 3i + 2j + 4k N and the displacement vector D = 2i - 3j + 5k m, we can calculate the dot product between these vectors.

The dot product of two vectors A and B is given by:

A dot B = (Ax * Bx) + (Ay * By) + (Az * Bz)

Calculating the dot product between F and D:

F dot D = (3 * 2) + (2 * -3) + (4 * 5)

= 6 - 6 + 20

= 20
