Involves ##\Gamma(1/4)##, right? -
TSny replied to the thread Motion in 2 dimensions.Yes, I agree. And the arc length comes out nice.

TSny replied to the thread Electric field due to arc shaped thin rod.I don't understand why you say that "dEx is Rcosθ distance away". Both dE and dEx are associated with the same point, namely the...

TSny replied to the thread Electric field due to arc shaped thin rod.Your answer is wrong because you can't get the x-component dEx by replacing R in the denominator of dE by Rcosθ. Note that Rcosθ < R...

TSny replied to the thread Electric field due to arc shaped thin rod.yes

TSny replied to the thread Electric field due to arc shaped thin rod.No. Let's forget dEx for now. Just concentrate on dE. dE is the magnitude of the electric field vector dE at the origin O produced...

TSny replied to the thread Electric field due to arc shaped thin rod.What was your reason for writing the denominator of the integrand as ##(R\cos \theta)^2##? This is not correct. To find ##E_x## due to...

TSny replied to the thread Electric field due to arc shaped thin rod.For the element of charge ##dQ## shown, how would you write an expression for ##dE## at the origin? How would you write the x-component...

TSny replied to the thread Motion in 2 dimensions.The vertical side of each triangle is the y-component of the velocity, which remains constant in time. The horizontal side is the...

Hmm yes it seems to me that as the x velocity becomes large that one must imagine this as zooming out on the diagram in such case the y...

To illustrate @PeroK's response. Think of a rock projected at an angle from the edge of a cliff. In the absence of air resistance, it...

In that scenario, the component of velocity in the y direction remains constant. It would not reduce to zero.

TSny replied to the thread Irodov- 1.123- Simple conceptual question with two masses connected by a spring.Yes. For any value of ##k##, you get the same expression for the minimum force necessary to cause movement of ##m_2##. [Edit: This...

It is interesting to think about ##k\to\infty## -
