The figure shows mass m moves with velocity u. Ring is restricted to move on smooth fixed horizontal rod. Velocity of the ring at that moment?
I thought the answer to be u/2 but the correct answer is 2u. This can happen if we take the rod to be the hypotenuse ie v(ring) * cos60 = u. please explain why?
Please solve
the question attached in the file
A collar of negligible size slides over the surface of horizontal circular rod for which coefficient of friction is 0.3.The collar is projected with a speed of 4 m/s and the radius of the ring is 10 cm.Find the distance moved by the collar before coming to rest.(g=9.8 m/s2)
What will be direction of force in fleming's left hand rule? It will be upward or downward.
hi sirs/madam
a liquid occupies half of a vessel at a particular temperature. the volume of the unoccupied part remaints constant at all temperature if alpha and gama are coefficients of linear and real expansion of a vessel and liquid, then gama equal to ...
kindly request you to give the solution with steps and thank you
i have certain doubts regarding some questions and the questions are as follows:--
1.)The electric field at 20 cm from the centre of uniformly charged sphere 10 cm is E.Then at a distance of 5 cm from the centre field will be?
2.)A uniform electric field pointing in +ve x direction exists in a region. let A be the origin,B be the point on x axis at x=+1cm and C be the point on y axis at y=+1 cm.then the potential at the pont A,Band C satisfy:
a.)VA<VB b)VA>VB c.)VA<VC d.)VA>VC
3.)A given charge situated at a certain distance from an electric dipole in the end on position experience a force F,a force acting on the charge will be?
Let P(r)=(Q*r)/∏R4 be the charge density distribution for solid sphere of radius R & total charge Q. for a point p,inside a sphere at a distance r1 from centre of sphere,the magnitude of electric field is?
