# A Force F = α + B X Acts on a Particle in the X-direction, Where a and B Are Constants. Find the Work Done by this Force During a Displacement from X = 0 to X = D. - Physics

Sum

A force $F = \alpha + bx$  acts on a particle in the x-direction, where a and b are constants. Find the work done by this force during a displacement from x = 0 to x = d.

#### Solution

Given that force is a function of displacement, i.e.

$F = a + bx$ ,
where a and b are constants.
So, work done by this force during the displacement x = 0 to x = d,
$W = \int\limits_0^d F \text{ dx }$
$W = \int\limits_0^d \left( a + bx \right) dx$
$W = \left[ ax + \frac{b x^2}{2} \right]_0^d$
$W = ad + \frac{b d^2}{2}$
$\Rightarrow W = \left( a + \frac{bd}{2} \right)d$
Is there an error in this question or solution?
