Using focused laser light optical tweezers can apply a force of about 15 pN to a 1.4 jim diameter polystyrene bead, which has a density about equal to that of water: a volume of 1.0cm^3 has a mass of about 1.0 g Part A Estimate the bead's acceleration gs tion in Express your answer using two significant figures. a=11 Incorrect; Try Again;4 attempts remaining

To estimate the acceleration of the polystyrene bead, we can use Newton's second law of motion, which states that the force applied to an object is equal to the mass of the object multiplied by its acceleration (F = ma).<br /><br />Given:<br />Force (F) = 15 pN = 15 x 10^-12 N<br />Mass (m) = 1.0 g = 1.0 x 10^-3 kg<br /><br />We can rearrange the equation to solve for acceleration (a):<br /><br />a = F/m<br /><br />Substituting the given values:<br /><br />a = (15 x 10^-12 N) / (1.0 x 10^-3 kg)<br /><br />a = 15 x 10^-9 m/s^2<br /><br />Therefore, the acceleration of the bead is approximately 1.5 x 10^-9 m/s^2.
