Your qstn. is however incomplete. U need to mention about theblock fully its position and velcoty or may ab accln. Or the sphere is rolling on to the block. Plz do mention and repost it for proer...
For minimum force a should be zero as net Force would eventually depends upon the system’s acclenration. Heence Force would be approx. minum when its accln = 0 And for Kinetic friction accln. is non...

tangent at any x distance would be => tanthetha =2x/a Now friction = umgcosthetha Balancing friction with mg*sin(thetha) we get, ucosthetha = sinthetha or tan(thetha) = u 2x/a = u x = au/2 The...
Dear Taral, Plz upload the attachment first to get the proper solution. Since it would be difficult to solve the problem without any figure.
Friction force would act tangentially obvious. Hence, f = umg Now, tanthetha = 2x/20 => x/10 sinthetha = x/root(x^2 + 100) Hence, mgsin(thetha) = f = umg 0.5 = x/root(x^2 + 100) x^2/(x^2 + 100) = ¼...
From Newton’s First law of eqn. we get, v = u +at 4 = 0 + a*6 a = 2/3 m/s^2 Force required = m*a => 5*2/3 = 10/3 N => 3.33 N Friction force = 0.25*50 => 25/2 = 12.5 N Net force => 12.5 – 3.33 => 9.22 ...
@ sumon no , quantum mechanics are too intresting but u need to understand it concept wise to make it stronger , u can study this in any of the research institutes of india , like iiser bhopal ,...
@ prakhar i am sorry , the ques are not clearly visible to me . and ask one ques in one thread , its complicated to explain the whole question set here , WAITING TO HEAR FROM YOU AGAIN
@ ajith i am not able to get your question , which frame u are talking about ?? is it any type of frame of reference , KINDLY LET ME KNOW YOUR QUERY IN A BIT MORE DETAIL
what is the problem mr write it i can see that proplem and try to answer it mr first mention it below ok i hope you are understanderd thank you
Motion is described in terms of displacement (x), time (t), velocity (v), and acceleration (a). ... The average velocity and average acceleration are defined by the relationships: A bar above any...
there are three members in truss When more number of members /supports are present than are needed to prevent ... For a truss with “m” number of two force members , and maximum 3 unknown
From Energy conservation we get, 1/2 mv1^2 - GMm/r1 = 1/2 mv2^2 - GMm/r2 …...........(1) and momentum conservation as no external forces are acting, m r1 v1 = m r2 v2 ….............(2) From Newton’s...
The standing wave eqn. is =>> y = Asin(wt + kx) For maximum displacment, dy/dx = 0 that is: Akcos(wt + kx) = 0 wt + kx = (2n+1)pi/2 x = (2n+1)pi/2k – wt/k
On Drawing the FBD of the rod and balcing the forces in vertical direcn. we get, 2Ncosthetha = M’g (Due to both wedge) and N =M’g/2cos(thetha) a = g
Friction is a force which is defined as: the obstruction or resitance any object feels/gets during its motion. Frame is a kind of reference or a consideraation includig x,y and axes respectivey....
Change in momentum = > Mvf – Mvi that is : deltaP = M(vf – vi) vi = root(2gh) = > 9.899 m/s vf = vi -gt => 9.899 – 9.8*0.1 = > 8.919 m/s Hence, deltaP = (50/1000)*(8.919 – 9.899) => -0.048975 That is ...
Taking the elevator as a reference frame. Now since elevator is a non-inertial frame pseudo force is applied. Since elevator is accelerating upwards therefore pseudo force acts in downward direction...
