Which of the following is the equation for work? a Fxd b Ext c dxs d dxt

## Step 1<br />In physics, work is defined as the product of the force applied to an object and the distance the object moves in the direction of the force. This is represented by the formula:<br />### **Work = Force x Distance**<br />## Step 2<br />In this formula, 'Force' is represented by 'F', 'Distance' is represented by 'd', and 'Work' is represented by 'W'.<br />## Step 3<br />Therefore, the equation for work is 'Fxd', which corresponds to option 'a'.
