oa is a rough surface whose equation is y = x2 [here x-axis is horizontal and y-axis is vertical]

oa is a rough surface whose equation is y = x2 [here x-axis is horizontal and the y-axis is vertical]. a small block of mass m is slowly pulled along the surface by an external agent from position o (0, 0) to position a (a, a?). if the coefficient of friction is you, the work done against the force of friction is

Detailed Solution:

This Question is Based On Work and Energy. It is coming from Neet and Jee Mains and IIT Advanced topic,

[Here x-axis is horizontal and the y-axis is vertical). A small
block of mass m is slowly pulled along the surface by
an external agent from position O (, 0) to position
A (a, a). If the coefficient of friction is u, the work done against
the force of friction is
B
(2) umg (1+ a)a
(1) umg a²ſ1 + a²
(3) umg/1+a?
(4) umga​
