If `n` is an even positive integer, then find the value of `x` if the greatest term in the expansion of `1+x` ^n may have the greatest coefficient als
Correct Answer - `x gt (n)/(n+2)` and `x lt (n+2)/(n)` If n is even, the greatest coefficient is `.^(n)c_(n//2)`. Therefore, the greatest term is `.^(n)C_(n//2)x^(n//2)`. `:. .^(n)C_(n//2)x^(n//2)gt.^(n)C_((n//2)-1)x^((n-2)//2)` and `.^(n)C_(n//2)x^(n//2) gt .^(n)C_((n//2)+1)x^((n//2)+1)`...

The greatest height to which a man can throw a stone is h. The greatest distance to which he can throw it will be
Correct Option is (B) 2h Greast vertical height is h Maximum Height \(v = \sqrt {2gh}\) Maximum Range \(R = \frac{u^2 sin \ 2 \ \theta}{g}\) \(R = \frac{u^2 }{g} sin \ 2 \ \theta\) \(\because v =...

Distinguish between elastic and inelastic collision.
No. Elastic Collision Inelastic Collision i. In an elastic collision, both momentum and kinetic energy are conserved. In an inelastic collision, momentum is conserved but kinetic energy is not conserved. ii. The total kinetic energy after collision...
