The linear momentum of a particle as a fuction of time 't' is given by , p = a +bt , where a and b are positive constants . What is the force acting on the particle ?

Explanation

Linear momentum of a particle , p = a + bt We know that force acting on a particle is equal to rate of change of linear momentum .
i.e., `vec(F)=(dp)/(dt)rArrvec(F)=(d)/(dt)(a+bt)`
`vec(F)=(d)/(dt)(bt)=b(d)/(dt)=bxx1=b`
